A Calibration Method for Consistency of Installed Optical Axis Applicable to Precision Optoelectronic Equipment

Abstract

The present invention proposes a method for calibrating the consistency of the installed optical axis of precision optoelectronic equipment, which can use theodolite, large-diameter collimator and special tooling to ensure the consistency of the installed optical axis of precision optoelectronic equipment, which can effectively Solve the deviation of the installed optical axis of different batches and sets of equipment under the original technical state, and avoid the problem of re-calibrating the installed optical axis of all equipment on the transport carrier after reinstallation or replacement of similar equipment. The method has the characteristics of simple operation, convenient use and high precision.

Description

technical field [0001] The invention belongs to the field of precision optoelectronic equipment, and relates to a calibration method suitable for the consistency of installed optical axes of precision optoelectronic equipment. Background technique [0002] Precision optoelectronic equipment (hereinafter referred to as "optical equipment") usually refers to the installation on aircraft, vehicles or ships and other transport carriers, which can effectively isolate external disturbances and maintain its internal optical devices, such as visible light TV, infrared thermal imager, laser measurement It is a comprehensive equipment for the task load such as distance plane to point to stable or precise follow-up pointing command in inertial space. With the rapid development of electronic information technology and other fields, the comprehensive performance of optoelectronic equipment has been greatly optimized. The farther you look, the clearer the identification becomes, so that i...

Problems solved by technology

Usually, the former is delivered to various task equipment manufacturers in the form of technical indicators for implementation, while the latter is generally realized by the final assembly unit after the installation and integration of unified calibration. Based on the above-mentioned precision decomposition process, equipment manufacturers currently pay more attention to their own machines. Axis pointing stability, little attention has been paid to how the final assembly unit performs unified calibration after the installation and integration, resulting in the installation and integration of the same batch of products, and even after the second installation and integration of the same product, its axis pointing relative to other task equipment is different. There are differences, and the resulting negative effect is that the common pointing consistency of the carrier multi-tasking equipment achieved by the overall unit through a large number of calibration work is easily lost due to the maintenance or upgrade of a certain equipment. After reinstallation, the overall unit had to invest manpower and time in recalibration, which brought great troubles to the daily maintenance and emergency repair of the carrier
