Description

The utility model relates to optical instrumentation and can be used in periscope observation devices and in the devices of a driver-mechanic of armored vehicles (BTT).

A periscopic day / night monitoring device is known - a combined observation device TKN-3 of the BTT commander (I.M. Goloshapov Tank night vision devices. M: Voenizdat, 1973. p. 23-28). The device contains a head prism, day and night surveillance devices. The daylight device consists of two parallel optical systems, each of which consists of a lens, reflectors, a wrapping system, a rhombic prism, and an eyepiece. The night device includes a lens, an electron-optical converter, reflectors, a wrapping system, rhombic prisms and eyepieces. To observe during the day in the daytime device or at night in the nighttime device, a swivel mirror is used. The rotary mirror connects alternately a day or night device for observation through rhombic prisms and eyepieces. The head prism, swivel mirror, rhombic prisms for adjusting the base of the eyes and eyepieces are common elements of the day and night devices.

The known device has a cumbersome optical circuit consisting of two independent channels of the daytime periscope device and the channel of the night periscope device using several reflectors, which leads to large dimensions and weight of the device. In addition, the device has a complex structure due to the use of wrapping systems to compensate and conjugate spatially remote optical elements of the optical circuit and create a direct image in the field of view.

A periscopic day / night observation device is known — CORDIS combined day / night periscope for observation (brochure CORDIS / CORDIS-E) of the company Fotona, Slovenia (Stegne 7, 1210, Ljubljana, Slovenia). The known device contains two stationary independent periscopic channels: day and night. The daytime channel contains optically coupled head prism and reflector. The night channel contains an optically coupled second head prism, a lens, an electron-optical converter mounted in the focus of the lens, and a bi-magnifier with a refracted optical axis. The optical axis of the day and night channels in the output part of the device are parallel and have different periscope. Each of the channels in the output part has its own working area for the eyes of the observer. The device case contains windows for optical channels and consists of the head and main parts connected by fixing threaded screws. Both head prisms are located in the head of the housing. When working during the day, the night channel is manually disabled by the switch of the electric circuit.

The known device has the following disadvantages. The large dimensions and mass of the head of the device due to the presence of two head prisms make it located outside the BTT, vulnerable to mechanical stress during operation, make it difficult to replace the head of the prism in case of damage, and limit the use of the device for different types of BTT. Different positions of the working areas for observation in the day and night channels in the output part of the device necessitate a change in the position of the eyes, and therefore, a change in the position of the observer's posture, which in real conditions of use causes him to become fatigued, or requires adjusting the position of the seat of the BTT driver. When observing the day channel, the night channel can be turned on involuntarily, which can lead to failure when it is turned on in the daytime. When observing into the night channel at night, the BTT is unmasked through the day channel using internal instrument lighting. To eliminate this, special additional protective measures are necessary. The connection of the head and main parts of the body with mounting threaded screws makes it difficult to quickly change the head prism when it is damaged and impairs the maintainability of the device due to the weakening of the threaded connection.

The closest to the claimed technical solution - the prototype - is a periscope device for day / night observation, a combined observation device for the BTT commander (certificate for utility model RU 19423, IPC G02B 23/08, F41G 1/40, priority date 04/26/2001) . The periscope device for day / night observation contains two periscope channels: day and night, located in the housing, consisting of head and main parts connected with cap locks with windows for optical channels. The device is made with one head prism for both channels. The daytime channel contains optically coupled head prism and reflector. The night channel contains an optically coupled head prism, a lens, an electron-optical converter mounted at the focus of the lens, and a bi-magnifier with a refracted optical axis. The reflector of the day channel and the combined lens, electron-optical converter and part of the night channel bi-magnifier elements are made with the possibility of moving and alternately installing these components on the optical axis. The movable elements of the day and night periscopic canals are rigidly interconnected and structurally made in one node. The optical axes of the day and night periscopic channels in the output part of the device are oriented at an angle to each other so that the working eye of the observer is common to both channels. The internal cavities of the head and main body parts are separated by a protective glass. Protective glasses are installed in the output windows of the day and night periscope channels.

The closest technical solution has the following disadvantages. The device does not allow receiving additional service information, except from day and night channels. Search performance with a single increase in the daily channel of the device is limited.

The objective of the utility model is to improve the quality and ease of use of the device, expanding the search characteristics of the device, maintaining the field of view of the daily observation channel.

The technical result due to the task is achieved by the fact that a multifunctional video monitoring device is introduced into the developed design, the search characteristics are expanded through the use of an integrated television camera. The periscope device for day / night observation comprises a housing of connected head and main parts, in which the day and night periscope channels are located. The periscope canal contains optically connected head prism and reflector. The night periscopic channel contains an optically coupled head prism, a lens, an electron-optical converter, the screen of which is combined with a CCD, and a television camera are installed in the focus of the lens. Information from the CCD is transmitted to a video monitoring device. The reflector of the day channel and the lens combined into the assembly, an electron-optical converter with a CCD matrix and a television camera are rigidly interconnected into a single movable unit and are made with the possibility of moving and alternately installing them on the optical axis. A television camera and an electron-optical converter are installed in parallel. The video monitoring device is installed in the housing so that the working area for the observer's eyes is common to both channels. The television camera has an autonomous switch and operates separately or simultaneously with an electron-optical converter. Information from it goes to a video monitoring device. A television camera is an additional source of information. Information from a television camera can be viewed simultaneously with the operation of the night channel.

The utility model is illustrated by the following graphic materials.

FIG. 1 Day periscopic canal.

FIG. 2 Night periscopic canal.

The periscope device for day / night observation contains a housing 1 made of two parts - the head and the main, connected with cap locks. A head prism 2 is installed in the head of the housing 1. A lens 3, an electron-optical converter 4 with a CCD 5, a reflector 6, a video monitoring device 7, a television camera 8 are installed in the main part of the housing 1. A protective camera is installed between the head and main parts of the housing 1 glass 9. The output window of the periscope channels 10 is closed with a protective glass. The working area for the eyes of the observer 11 is located in the image space of the device. The head prism 2 and the reflector 6 mounted on the optical axis form a day channel. In this case, the output optical axis of the daytime channel is oriented at right angles to the optical axis formed by the head prism 2. Head prism 2 mounted on the optical axis of the lens 3, an electron-optical converter 4 with a CCD 5 mounted in the focus of the lens 3, form a night channel. A television camera 8, installed in parallel with the electron-optical converter, is located in a single unit with night channel elements and is an additional channel. The reflector 6 of the day channel and the lens 3 integrated into the assembly, an electron-optical converter 4 with a CCD matrix 5, a television camera 8 are rigidly interconnected, combined into a movable unit 12 and made with the possibility of moving and alternately installing them on the optical axis. The channel switching is carried out by the handle 13. The video monitoring device 7 is located in the housing so that its screen can be viewed from the working area for the eyes of the observer 11. The working area for the eyes of the observer 11 is common to all channels.

The television camera 8 is located in a single unit with the elements of the night channel. Information from it arrives at the video control device 7 in standalone mode or together with information from the night channel. A television camera is an alternative electronic channel with additional features (monitoring from a TV screen): electronic zoom, improved search performance, increased field of view.

The device operates as follows.

When the “DAY-NIGHT” channel switching handle 13 is set to the “DAY” position, the movable unit 12 is moved in such a way that a reflector 6 is mounted coaxially with the head prism 2, and a daytime periscope channel is formed, and the elements of the nighttime channel - the lens 3, the electron-optical transducer 4 with a CCD matrix 5 and the television camera 8 are output from the optical channel and fixed outside the optical axis. The image of the observed area is viewed through the protective glass of the day channel 10 by placing the eyes of the observer in the working area. When you set the switch channel 13 "DAY-NIGHT" to the position "NIGHT", the movable node 12 is moved so that the optical axis coaxially with the head prism 2 sets the elements of the night channel - the lens 3, the electron-optical transducer 4 with a CCD 5 and a television camera 8. The reflector 6 is removed from the optical channel and fixed outside the optical axis. The image of the observed area is considered by the observer on the screen of the video monitoring device 7 through the working area for the eyes of the observer 11. The working areas for the eyes of the observer of all channels are conventionally aligned and are alternately formed in the image space of the device convenient for observation.

Thus, the presence of new elements in the device improves the quality and convenience of its operation, expands the search characteristics of the device.
