Description

Indicator of optical and optoelectronic glare objects

The utility model relates to techniques for remote detection and determination of coordinates of optical and optoelectronic devices, such as binoculars, telescopes, cameras, video and movie cameras, shooting optical sights, etc.

Known optical locator, which includes a radiation source with a pulsed laser and integrity, with which probing signals are fed to the location object, as well as a receiving device with a telescope, a light filter, reference and object channels, a hologram processing unit associated with the control system (SU 944437 , G 01 S 17 / -6, 04.20.1995).

This device provides an increased likelihood of recognizing glare objects due to the high quality of visual images. However, its disadvantage lies in the constructive complexity that predetermines low

operational reliability.

Closest to the proposed one is an indicator of optical and optoelectronic glare objects containing a radiation source with an LED illuminator and a receiving device, which includes a photodiode array and a processing unit for processing incoming signals (US 5629704 A, G 01 S 7/483, 13.05. 1997).

The disadvantage of this device is also associated with the complexity of the design.

The objective of the utility model is to simplify such an indicator while maintaining the effectiveness of its functioning.

The problem is solved in that the indicator of optical and optoelectronic glare objects containing a radiation source with an LED illuminator and a receiving device includes a beam splitter located on the optical axis between the radiation source and the glare object, the illuminator is capable of monochromatic radiation at several lengths waves and is installed in the focus of the collective lens, and the receiving device includes a coaxially located rotary mirror, optically coupled to a beam splitter m, a filter and a telescope, and the optical axis of the radiation source and the receiving device are oriented in parallel.

Partial essential features of the utility model contribute to the solution of the problem.

The illuminator of the radiation source is made in the form of a composite double-emitting diode with red and green colors with the possibility of alternating switching on the emitting elements, and the filter of the receiving device is two-color with transmission of radiation of the two named colors. The illuminator of the radiation source is made in the form of three separate

LEDs of red, green and blue radiation with the possibility of alternating switching on of the radiating elements, and the filter of the receiving device is tri-color with transmission of radiation of the three named colors.

The drawing shows a functional diagram of the proposed device.

The indicator contains a radiation source with an LED illuminator 1 and a collective lens 2, a beam splitter 3, a receiving device with a swivel mirror 4, a transmission filter 5 and a telescope 6. Position 7 on the diagram indicates a glare object to be detected. The illuminator 1 of the radiation source is capable of monochromatic radiation at several wavelengths and is installed in the focus of the collective lens 2. The beam splitter 3 is located on the optical axis between the radiation source and the glare object 7. In the receiving device, a rotary mirror 4, optically coupled to the beam splitter 3, the filter 5 and the telescope 6 are aligned. The optical axis of the radiation source and the receiving device are oriented in parallel.

The lighter 1 of the radiation source can be made in the form of a composite LED of double radiation with red and green colors, and the filter of the radiation receiver - two-color with transmission of radiation of the two named colors. The illuminator 1 of the radiation source can also be made in the form of three separate LEDs red, green

3 and blue radiation, and the light filter of the radiation receiver is tri-color with

transmitting radiation of the three named colors. In each case, the illuminator 1 of the radiation source is configured to alternately turn on the radiating elements.

The device operates as follows.

In the process of searching for a flashing object 7, the LED illuminator 1 produces monochromatic radiation probing the surrounding space. When object 7 is detected, radiation of maximum intensity reflected from it passes along the optical axis of object 7, and then through a beam splitter 3, a rotary mirror 4, a filter 5 and a telescope 6 gets to the observer.

In the modification of the indicator with the illuminator 1, made in the form of a double-emitting diode, red and green colors are used, as already indicated. The filter 5 is also two-color (with two sections) and transmits radiation of these colors.

In the modification of the indicator with the illuminator 1, made in the form of three separate LEDs, red, green and blue colors are used. The color filter 5 is also tri-color (with three sections) and passes the named colors.

The radiating elements in the illuminator 1 are switched on alternately for a time equal to 0.2 - 0.5 seconds. At the same time, the corresponding sections of the filter 5 function in turn.

4 Use in illuminator 1 for each radiation of a narrow range

wavelengths, and in the receiving device of the filter 5 allows for a more spatial search of the object 7 than, for example, when the illuminator 1 is in the form of a halogen lamp, and it is more contrast to fix the glare object 7.

The use in the illuminator 1 of two and, especially, three colors of radiation predetermines the expansion of the observed spectrum, which virtually eliminates the possibility of secrecy of the glare object 7 by installing barrage filters in it.
