Device for protecting the eyes from harmful light or radiation sources

description

The invention relates to a device to protect the eyes from harmful Lichtbzw. Radiation sources, particularly intended for protection against laser beams.

State of the art

To protect the human eye from laser beams two types of laser serschutzbrillen used until now. Goggles reflect or absorb a laser beam in the infrared, visual or ultraviolet wavelength range all the way up to an upper limit or duration pulse energy output for a given laser pulse number or duration. The human eye is completely protected from Goggles in the appropriate wavelength range. However, the existing technology reaches its limits with ultra-short laser pulses, especially when focusing elements in the structure occur. Justierbrillen weaken laser radiation in the optical wavelength range by the filter to such an extent that it is visible to the human eye, but is not dangerous. In both cases, special glasses are used, which have a negative impact in several respects.

The complicated production process for full goggles and Justierbrillen regularly leads to high costs, typically more than 400 euros per piece. The protective glass used for Goggles and Justierbrillen exerts its effect only for a specific narrow range of wavelengths, so that disadvantageous each specially adapted for various laser, different glasses must be used. Laser safety eyewear are currently available based on coated reflecting or absorbing massive filter glass to glass or plastic base.

The colorful protective glass, the environment for the viewer in the wrong colors is provided DAR and the light transmission of the remaining ambient light is usually greatly reduced. That the laser beam with a full safety glasses can not be seen, also complicates the practical work, for example during adjustment of the laser beam, and requires frequent change of glasses. Due to their mode of action of the existing goggles technology always causes only a weakening of the laser radiation (albeit over many orders of magnitude), so the effect is always limited and a higher protective effect can only be achieved by using thicker filter glasses. However, this is usually associated with cost increase, weight increase and decrease of daylight transmission, so go with loss of comfort and cost disadvantages associated.

In addition to these conventional laser goggles and ideas to devices for indirect observation of laser beams have been developed. From US 8,334,899B1, a device with a video camera is known which can be attached to the head of a user and can be captured with the laser beams having different wavelengths. This video camera is connected via a cable to a video monitor, which can be arranged in the field of view in front of the eye of the user.

By using a video camera, it is generally only possible to record image information in the visible range. Desirable for dealing with laser beams in the laboratory would be also signals of electromagnetic waves whose wavelengths are outside the optical wavelength range to detect, or to provide DAR on the screen. Furthermore, when working with laser beams in the laboratory, it would be advantageous to specifically weighted signals from different regions of the electromagnetic spectrum in the representation on the display device or completely different hide. From a cost perspective, it is in this case to desirable to rely on existing technology and ten to HAL, the number of components required minimum.

task

The object of the invention to provide a device for protecting the eyes from harmful light or radiation sources ready, which makes it possible that the eye it is in use dec is the area to be observed around perceives in almost the same way as without the device , particularly with respect to the viewing direction, color and distortion. In addition to the invention made visible laser beams having wavelengths outside of the optical spectral range and signals of different regions of the electromagnetic spectrum can be weighted differently on the display so-, such additional information can be displayed. Advantageously, the device should also recognize pumping flashes and can suppress.

Solution of the problem

The objects of the invention are achieved by a device having the features ACCORDING main claim. Advantageous embodiments of this can be found in each of the dependent claims referring back. The invention

The invention relates to a device for protecting the eyes from harmful light or radiation sources, and in particular against laser beams. The device comprises at least one sensor assembly, a means for digital processing of the image information generated by the sensor assembly, at least one display device for displaying the digitally processed image information, and a holder for receiving the at least one sensor module and the at least one display device.

In the context of this application rich wavelengths in the range of 380 nanometers are to be understood to 780 nanometers below the optical wavelength or spectral range. Under the infrared wavelength or spectral range of wavelengths between 780 nanometers and 1 mm are to be understood. Among the ultraviolet wavelength or spectral range of wavelengths between 100 nanometers and 380 nanometers are to be understood. Further, the visible spectral region between, the distinction of the optical spectral region, and the non-visible spectral range, which includes all other wavelengths, in particular also the IR and UV range.

The sensor assembly is at least capable of recording spatially resolved information about the incident ambient light for a defined wavelength range of the electromagnetic spectrum. The sensor assembly consists of at least one sensor for this purpose. In addition, the device even more, additional optical components, which reflect the vicinity to the sensor or parts of the sensor or may also have filtering properties. The sensor is mounted to the support structure and this, if necessary, on the human head so that the sensor image information of the region to be observed of interest can absorb. The sensor may be (Charge-Coupled, (Electron-Multiplying CCD), ICCD (intensified CCD) Active Pixel Sensor (also referred to as CMOS sensor CCD to image sensors (z. B. Sensor Device) EMCCD generally, for example, is installed in smartphones), also with amplifiers (z. B. microchannel plates (MCP), image intensifier, and image intensifier tubes) may be coupled to act.

Also the use of other types of sensors for detecting surroundings is possible, for example, active sensors that enable the detection of the spatial area (z. B. Kinect camera, ultrasonic sensors or light field cameras). In addition to the above-mentioned sensors, which are mainly suitable for detecting the electromagnetic visible wavelength region and adjacent regions, the use of imaging sensors for other spectral regions is possible, for example by infrared / thermal imaging systems or of miniaturized gamma cameras.

Further, arrangements or arrays may be used from various sensors, which are sensitive in different spectral ranges, if appropriate, to gather information inside and outside the optical range. This can be advantageous when working with lasers, the wavelengths of which lie outside of the optical Spekt- ralbereichs.

It is also possible to filter out information from certain wavelength ranges or spatial regions of interest and to extract information in the processing of the signals to be weighted, or differently in order to allow a precise work with Laserstrah- len. To this end, optional color filters may be used, which are arranged in front of one or more sensors, and for example only are permeable to narrowly defined wavelength ranges.

Furthermore, beam splitter or intensity filter can be used as additional optical component application, so that the intensity of the incident light on the sensor can be adapted to the dynamic range of the respective sensor or sensor area and monitoring settings by the simultaneous use of several sensors, and various slow-down for the respective sensors, a observation of the environment allows many dynamic ranges of the respective sensors.

Such a beam splitter arranged in front of a sensor is shown schematically in FIG. 1 The incident light (1) is divided by a beam splitter (2). A portion of the light is modified by a filter (3) and by a first sensor (4) registers. The other part of the light is registered by another sensor (5).

The optional additional optical components such as lenses, mirrors, beam splitters, filters for the attenuation, polarization, and wavelength selection and prisms can be used advantageously to keep the size of the apparatus compact or radiation with certain wavelengths or optical properties such. B. polarization to specifically draw attention to the sensitive in these wavelength ranges sensors or sensor regions of the device. For this purpose, these optical components are advantageously each on or before egg nem sensor or a sensor assembly disposed.

Such optional additional optical components can be particularly used to map different filter settings on different portions of an image sensor. You can also enable the mapping of spatial regions around to portions of one or more sensors such. Example, to the left and right halves of a sensor or camera chips. This cost and weight can be saved and miniaturization are achieved. The inventive agent for digital processing enables the combination and processing of the information obtained from the sensor assemblies or other external data sources via the environment

The image information captured by the one or more sensor assemblies are digitally processed by a digital processing means, such as a computing stage so, so that they can subsequently be transmitted to a display device and displayed on this device in a recognizable for the eye shape. In this digital processing means the image information can be, for example, be a software application similar to applications in the field of digital cameras, which mation the Sensorinfor- for display on the screen processed (z. B. color correction, contrast increases etc.).

(Z. B. called. Barrel correction) are further undesirable distortion effects such as may occur for example by use of lenses to sensor or user side computationally compensated. If several sensors are available or sensor regions used different processing enables processing of various sensor information to an image, that is, for example, an image with an increased dynamic range, which represents both the dark environment of a vacuum chamber and at the same time the very intense laser pulse within the vacuum chamber. This can be done separately in a simple design for the entire image or for individual image areas to pixel by pixel.

used are sensors which are sensitive inside and outside the optical range, to enable said means to process the information together and displayed on a display device. In this processing, it should enable said means to be weighted for precise work with laser beams information trainees dazzle or different. The Summary and weighting of image information by software applications is known for example from US 5828793rd Such software applications are used inter alia as a visual aid in the so-called "digital eye glasses" or in so-called "EyeTaps".

The display unit is able to present the digitally processed signals to a user's eye seen in real time. For example, the screen of a digital camera or a smartphone with the associated electronic components can be used as such a display device. The use of projectors (micro nibeamer), heads up displays (HUD) or contact lenses with built-in screen are possible.

The holder is adapted to fix the at least one sensor assembly and the at least one display device to a human head, and to ensure adequate protection against the harmful radiation, particularly the laser radiation. Since the invention described herein does not require that the holder have openings or have to be transparent this is very easy to achieve by various cost and / or lightweight materials. In an advantageous embodiment, the holder may consist of a plastic frame and a drawstring. The plastic frame is shaped such that the sensor and the display device can be inserted into the plastic rack or inserted or can be fixed to the plastic frame in other ways. The drawstring can be fixed to the human head, the plastic frame. It can be moun- ted on the sides of the plastic frame and for example, run from one side of the plastic frame of the back of the head along to the other side of the plastic frame.

If a user uses the apparatus according to the invention, the holder may at the head of the user advantageously be fitted so that at least one sensor assembly and a display device in each of the visual axis of an eye of the user are arranged and to cover the largest possible area of ​​the visual field. Characterized this eye is protected from the effects of possible harmful radiation, in particular laser radiation. Only the radiation of the at least one display device meets with a device depending on the display type of construction limited intensity on the eye. By arranging the transmitter sors in the viewing direction of the viewer, the viewing angle can be picked up by the sensor and displayed using the display apparatus also advantageously precisely that the viewer would see without a device.

In an advantageous embodiment, the holder additionally shields from the areas of the eyes, which are not covered directly by the sensor or the display device. For this purpose, the holder is configured optically opaque at least at those locations. Thereby, the lateral penetration of a laser beam, and the stray light from entering into an eye can be prevented, for example. The properties, for example, the thickness of the material are chosen so that the corresponding laser safety requirements are met.

Alternatively, the support can for example also on a helmet or a cap be attached, which can be placed on the head of an observer.

In another embodiment, the apparatus via logarithmic sensitive sen- sors can have. These sensors are not the values ​​of the intensity of the radiation incident on the sensor itself, but logarithmic values ​​of intensity are regularly the values ​​of the logarithm to the intensity, passed by the sensor.

Also possibilities for losing optional sensor assemblies are conceivable examples game as observed at a certain point the beam and work elsewhere.

By the accounting step the combination of information from different sensor assemblies can be beneficial. This is discussed way of example below:

In one embodiment, over-exposed frames may (frames) are hidden or in the image processing by the means for digital processing of the signals calculated out, z. if flash lamps are used in the laboratory, of which having a predetermined frequency to high intensity radiation, such as. for example, As flashes of light is emitted. To this end, the intensity of the individual images is calculated and displayed the previous image of another frame in the event of a significant overload, for example in real time.

Further, by the accounting step possible to combine the record the laser radiation with small light-sensitive sensors, the sensor data from light-sensitive sensor groups that filter out the laser radiation. Thus, observation of areas in a design and the monitoring of the laser radiation is possible. By existing on the glasses controller, the composition can be specifically controlled.

The mode of action of such an agent for digital processing is shown in Figure 2, wherein by way of example two different cases for the image reconstruction (R) are indicated. are shown in the upper half of Figure 2 taken along the timeline t are three frames for the case a) the operation of a sensor and for the case b) the operation of two different photosensitive sensors.

In case a) the intense light of the laser flash lamp leads at the time t2 to overexposure. This is detected and the process stage (P) instead the image sensor from time t1 displayed. At the time t3 S1 is no longer overexposed and the signal reappears. At high frame rates so unpleasant flickering is to be prevented.

In case b) there is initially the same situation as in case a). The intense light of the laser flash lamp leads to overexposure of the first sensor. However, here is a further sensor (S2) is available, which greatly weakened the light, so that at times t1 and t3 to detect a signal from S2. This recognizes the computing stage P and displays the data from S1. At the time t2 S1 is overexposed. Here P is now represents the image of S2.

In a further embodiment, the device may advantageously be designed as a modular system which allows easy replacement of individual components, such as filters and / or sensors. This would have the advantage in particular that the inventive device could easily be adapted to different gen laser or other Rahmenbedingun- without the need for a completely new device would be required.

In another embodiment, high-resolution sensors, that is sensors having a pixel number of more than ten megapixels, for observing properties of the laser beam such. B. the beam profile, can be used. Here, filter wheels can be used or continuously variable gradient. These can be set by the user optimized for beam observation.

In order to increase the wearing comfort, the display device can be made in a further embodiment of a screen, and an optical assembly, wherein the screen is in front of any eye of the user, but the image generated by the screen shown recognizable by the optical configuration for at least one eye.

In a further embodiment, additional means may be provided which allow that, in addition warnings on the display device are displayed, recognized when for example the temperature measured by the sensor radiation exceeds a predetermined maximum threshold of intensity. This warning could be to display the measured intensity value in a partial area of ​​the display device in red in front of a suitable background, possibly associated with an audible warning, or only a warning in the form of a respective color field (z. B. red or green) the Anzei- gegerät to show.

In another embodiment, on the display device using the principle of augmented reality, which is the computer-based supplement of pictures and video images of the environment through more ads or graphics, in addition information, such as information of measuring instruments are displayed on the display device or an optical assembly.

If the goggles fitted with active sensors, such as with a Kinect sensor, the virtual on-screen display can also verwen- for input by measuring the hand position can be det (virtual keyboard, virtual meter).

In a further embodiment, the device may optionally be also connected via a dead-man with the laser system. This advantageously leads to the fact that the laser system is switched off when the display device is detached is critical (for example by a Anpressdrucksensor the device at the head of the observer) or the battery power of the device.

The power supply of the device can be advantageous assured of accumulators, as are used in mobile devices. These can be replaced by redundant systematically me, for example, a disposable battery that is used when the battery is empty or a second battery can be switched on. A modular system is conceivable that allows easy exchange of batteries during operation, or with minimal disruption to a dedicated cradle.

In a further embodiment, the device may have control knobs or on-screen menu to control the functions of the protection device. This can be basic settings like screen brightness, alert sound volume etc. but also include broader provide interactive functions, such as filter setting and weightings in the composition of various sensor data to off given image (eg "brightness laser sensor. 30%, brightness around 70 % "). also, an input using data gloves would be possible.

In an easy to implement embodiment of the invention, conventional and therefore cheap cameras can be with built-in screen as sensors and display devices turns comparable. This can be much cheaper than conventional special glasses Laser goggles. A camera is suitable regularly to take video footage of the area to be observed around in real time and in real colors. The screen can display these video recordings advantageous in real colors. As real colors of the objects around those colors will be referred to herein which produce the wavelengths of light emitted by these objects radiation in the optical wavelength range sufficiently similar color impression on the human user. In other words, this meant that the user of the goggles can make possible no color difference of the environment considered when using the device of the invention over the consideration without this device.

In a further embodiment of the invention, the camera and the screen of a smart phone can be used. This is by the holder, for example a plastic injection-holder with a foam pad to the optically impermeable seal at the edges, arranged one in front of a user's eye. The other eye can be covered by the optically opaque support and are thus protected from the laser beam. In this embodiment, the camera and display are integrated in one device. Digital image processing, the regular existing smartphone software applications can be used. In another embodiment, a Smartphone is arranged in front of a respective eye through the bracket ever. In this embodiment, the impression of depth can be mediated by the spatially displaced images of the smartphone advantageous. This makes the estimates of distances are possible and would be beneficial for the practical work in a laboratory.

In a further embodiment is arranged an additional optical lens shiftable between at least a smartphone and the corresponding eye of the observer at least. are the recordings of the camera displayed on the screen of the smartphone may, in particular through an optical lens as a converging lens even at small distances between the screen and the viewer's eye overall visible to the eye makes. In addition, optional visual defects could therefore be corrected.

In another embodiment, the plastic frame mentioned above has a framework in which a smart phone can be inserted. The smart phone is arranged so that one half of the screen of the smartphone in the visual axis of an eye is depending. To obtain a spatial impression for both eyes from the existing standard on a smartphone back individual image sensor of the camera, the camera field of view is divided by an optical setup before the smartphone camera. For example, the field of view of a vertical half of the sensor pixels can be deflected by a second mirror and How-with a displacement of the are aligned parallel to the second vertical half by a mirror prism. By further optical components such as lenses, the construction can be kept compact. In this way, the measurement is possible by the observation with attached at two positions corresponding sensors. Through this offset observation of the environment can be advantageously created a spatial impression. In particular, it is thus possible to divide the image area of ​​a smart phone camera so that the distance between the two sensor surfaces corresponding to the eye spacing of the user. This is schematically illustrated in FIG. 3

In a further advantageous embodiment of the invention may additionally contain a USB on-the-go (OTG) input device or Bluetooth input device to a smart phone so CONNECTED sen that the control of the functionality without removing the holder, in particular a pair of glasses is possible.
