Abstract
The utility model discloses a device of improving laser dodging effect and restraining speckle based on a rotating mirror technology, comprising a laser, a reflector, a rotating shaft, a motor for controlling rotating speed and a dodging system. One end of the rotating shaft is connected with the reflector and the other end is connected with the motor, the motor controls the rotation of the reflector via the rotating shaft, and a 87 to 90-degree non-orthogonal included angle exists between the rotating shaft and the reflector. The device employs the rotating reflector technology, the laser sends laser to the reflector, and along with the incident angle variation and by being reflected to a receiving surface, the laser is not a light point any longer but is a light ring, and then is carried out the dodging processing via the dodging system, so that the laser dodging effect is improved. The beneficial effects of the utility model are that by employing the rotating mirror technology and changing the laser incident angle, the reflected laser changes continuously, so that the dodging effect can be improved and the speckle shaped speckle can be restrained, and the device of improving laser dodging effect and restraining speckle based on the rotating mirror technology has the advantages of being low in cost and simple in technology, etc.
Description
Technical field
The utility model relates to laser technology and shows the field, relates in particular to a kind ofly to improve the even light effect of laser and suppress speckle device based on the rotating mirror technology.
Background technology
Following advantage has been compared in laser television with traditional tv: in bright gay color degree well, brightness is high, resolution is high.It has replaced traditional light source from brightness, color gamut space, and there have been very big raising in power consumption and life-span.Because the extremely narrow and high spectral brightness of spectrum of laser is so that laser can produce great color gamut space as light source, so that colour gamut can reach more than 90% of human eye.It is the very big progress that TV shows the field.
But because the intrinsic time domain of laser and the interference in spatial domain, Ear Mucosa Treated by He Ne Laser Irradiation can produce either overt or covert granular speckle during to coarse body surface, and speckle has had a strong impact on the resolution of image.Be generally round spot or round dot from the light pencil of laser emitting at receiving plane, can't Direct Uniform larger area of illumination or space, so in such as fields such as Laser Processing, laser lighting and demonstrations, then need laser beam is spared light and shaping.And existing light-uniforming technology cost is very high, and device is complicated, and this is an important restriction factor that hinders the development of laser television.
The utility model content
The purpose of this utility model is exactly in order to address the above problem, providing a kind of improves the even light effect of laser and suppresses speckle device based on the rotating mirror technology, by adopting the rotating mirror technology, change the laser incident angle, the method that the laser of reflection is constantly changed is improved even light effect and is suppressed mosasic speckle, and it has, and cost is low, technology simple, improve the advantage that the even light effect of laser can suppress speckle simultaneously effectively.
To achieve these goals, the utility model adopts following technical scheme:
A kind ofly improve the even light effect of laser and suppress speckle device based on rotating mirror, the motor and the even photosystem that comprise laser instrument, catoptron, rotating shaft, control rotating speed, the laser that laser generator sends shines on the catoptron of rotation, laser through mirror reflects shines dodging device, spare light by even photosystem again, rotating shaft one end links to each other with catoptron, and the other end links to each other with motor, and motor is by the rotation of rotating shaft control catoptron.
Described mirror shapes is circular, is constantly rotated by Electric Machine Control, is used for reflecting the laser light to the face of acceptance, and when catoptron did not rotate, laser was a round dot to receiving plane, and when it constantly rotates, made laser become the laser ring to receiving plane.
Described rotating shaft and catoptron have the angle of an on-right angle, and angle is unsuitable too small, and 87 degree are comparatively appropriate to 90 degree.
Described motor is the device that rotates by rotating shaft control catoptron, and its rotating speed turns at per second 50 to 100 and gets final product.
Described laser generator can be solid state laser, gas laser, liquid laser or semiconductor laser, and laser beam is sent in its groundwork exactly.
The beneficial effects of the utility model: by adopting the rotating mirror technology, change the laser incident angle, the laser of reflection is constantly changed, can improve even light effect and suppress mosasic speckle, and have the advantages such as cost is low, technology is simple.

Wherein, 1. laser generator, 2. catoptron, 3. rotating shaft, 4. motor, 5. even photosystem, the 6. laser of incident, the 7. laser of reflection, the 8. ring of light.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, the LASER Light Source that laser generator 1 sends shines on the catoptron 2, and catoptron 2 and rotating shaft 3 out of plumb have one 87 degree to 90 angles of spending.Because catoptron 2 constantly rotates, the incident angle that laser shines on the catoptron 2 constantly changes, the laser beam direction of reflection is also in continuous variation, the laser that reflexes to receiving plane no longer is a laser spot, but laser ring of light 8, spare light by even photosystem 5 on this basis, improved the even effect of light of laser.Constantly change to the direction on the receiving plane owing to laser beam simultaneously, therefore the position of speckle also is constantly to change, and in certain human eye limit of integration, the speckle that light and shade is different is superimposed, utilize the eye storage characteristic of human eye, from the subjective effect that suppresses speckle that reached.Catoptron 2 links to each other with rotating shaft 3, and motor 4 is by the rotation of rotating shaft control catoptron, and rotating speed is the problems such as per second 50 to 100 turns and can reach requirement, and the power consumption of having avoided high rotating speed to bring is high, noise is large.
As shown in Figure 2, rotating shaft 3 one ends link to each other with motor 4, the other end links to each other with catoptron 2, rotating shaft and catoptron angle are between 87 to 90 degree, motor rotates by rotating shaft 3 control reflecting prisms 2, reflecting prism 2 reflections of the laser of incident through rotating, it no longer is a point that the laser 7 after the reflection shines on the receiving plane, but has formed a laser ring of light 8.
As shown in Figure 3, catoptron 2 has an angle with rotating shaft 3, and angle can not be vertical, otherwise the laser direction after the reflection can not change, and can't form the laser ring of light.Angle is unsuitable too small, otherwise can cause laser too to disperse, and angle is comparatively suitable between 90 degree at 87 degree.
Although above-mentionedly by reference to the accompanying drawings embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
