Abstract

Оптико-механический модулятор добротности с функцией коммутатора (ОМЗ-К) представляет собой устройство, включающее оптико-механический блок, блок питания и процессор управления, а также сборную призму, которая устанавливается на вращающемся роторе электромотора, состоящую из двух прямоугольных призм Ap90, закрепленных гипотенузными гранями на наклонных гранях ромб-призмы с расчетным плоскопараллельным зазором между этими гранями, отличающийся тем,что обеспечивает добротность контура импульсного лазера в момент излучения, в двух направлениях, благодаря нанесенным полупрозрачным покрытиям заданных параметров на катетных гранях призм Ap90, закрепленных на ромб-призме, вместе с глухим зеркалом, входящим в конструкцию лазера, который не создает в момент излучения засветок на сенсоры, принимающие эхо-сигнал с каждого из двух возможных направлений, что обеспечивается вращающимся обтюратором, закрепленным на роторе электромотора, который прикрывает сенсоры в момент излучения лазера и пропускает пришедший эхо-сигнал на приемные сенсоры, за счет наличия на кромке обтюратора двух вырезов для пропуска на сенсоры приходящего эхо-сигнала.An optical-mechanical Q-switch with a switch function (OMZ-K) is a device that includes an optical-mechanical unit, a power supply and a control processor, as well as a combined prism, which is mounted on a rotating rotor of an electric motor, consisting of two Ap90 rectangular prisms fixed by hypotenuse faces on the inclined faces of the rhombus-prism with a calculated plane-parallel gap between these faces, characterized in that it provides the quality factor of the contour of a pulsed laser at the time of radiation, in two directions due to the applied translucent coatings of the given parameters on the Ap90 prism side faces attached to the rhombus prism, together with a dull mirror included in the laser structure, which does not create light at the moment of emission of light on sensors receiving an echo signal from each of two possible directions This is ensured by a rotating shutter mounted on the rotor of the electric motor, which covers the sensors at the time of laser radiation and passes the received echo signal to the receiving sensors, due to the presence on the edge of the shutter high cut-outs for skipping the incoming echo signal to the sensors.

Claims

An optical-mechanical Q-switch with a switch function (OMZ-K) is a device that includes an optical-mechanical unit, a power supply and a control processor, as well as a combined prism, which is mounted on a rotating rotor of an electric motor, consisting of two Ap90 rectangular prisms fixed by hypotenuse faces on the inclined faces of the rhombus-prism with a calculated plane-parallel gap between these faces, characterized in which ensures the quality factor of the pulse laser circuit at the time of radiation, in two directions, due to the applied translucent coatings of the specified parameters on the leg faces of Ap90 prisms mounted on the rhombus prism, together with a dull mirror included in the laser structure, which does not create flares at sensors receiving an echo signal from each of two possible directions, which is provided by a rotating obturator mounted on the rotor of an electric motor, which covers the sensors at the time of laser radiation and I come down on the echo signal reception sensors, due to the presence on the edge of the obturator two slots for passing the sensors on the incoming echo.
