Angle reference laser digital sensor

Abstract

This invention refers to angle reference laser digital sensor, which contains laser set on casing top, casing, optical facula modulation system, liquid double optical wedge compensator, PSD position photoelectric sensor and signal output line connected to outside of casing, the principle of said invention is that the laser beam specially modulated by optical system automatically generates high precision vertical laser beam, the standard deviation reaches 1 / 600000, the compensation precision greatly exceeds the traditional technology with real time outputted digital signal.

Description

Technical field: [0001] The invention relates to an angle reference measuring device. Background technique: [0002] In the military, any problem involving the automatic adjustment of the launch angle, such as anti-aircraft artillery, missile launch vehicles, tracking radars with automatic rotation angles, and positioning systems for ships, submarines, and distant survey ships, all involve solving the zero reference problem , the vertical or horizontal datum. At present, the anti-aircraft artillery has changed from traditional manual operation to automatic digital operation. The automatic adjustment of the gun barrel has been controlled by the digital signal of the angle encoder, but the reference (zero reference) of the elevation angle is still manually adjusted by the traditional long water bubble. The problems in this method are: first, the long-bubble reference change cannot provide digital signals to the control system commander; second, the gun body reference is subje...

Problems solved by technology

At present, the anti-aircraft artillery has changed from traditional manual operation to automatic digital operation. The automatic adjustment of the gun barrel has been controlled by the digital signal of the angle encoder, but the reference (zero reference) of the elevation angle is still manually adjusted by the traditional long water bubble. The problems in this method are: first, the long-bubble reference change cannot provide digital signals to the control system commander; second, the gun body reference is subject to severe vibration during the design process, which is a constantly changing quantity , and the change of this benchmark cannot be notified to the director in real time, resulting in a significant reduction in the design hit rate

The zero reference of tracking radars and missile launching vehicles is also generally adjusted manually with long water bubbles. The same problem exists in anti-aircraft guns. The positioning systems of ships, submarines, and distant survey ships cannot completely use the US GPS global positioning system. Only my country's own positioning system can be established, but the current problem is that the error of the inertial navigation zero reference is relatively large, and hydrostatic calibration is required before each mission, which brings about a large economic and personnel consumption. The main thing is that the zero reference cannot be determined in real time and with high accuracy
