1. Introduction
Multi-Spectral Multi-Axis Test Equipment is a specialized test platform for research, adjustment and verification of multi-channel optoelectronic systems. It integrates laser optical-axis test, infrared optical-axis test, visible-light optical-axis consistency test, moving-target simulation, laser ranging simulation and laser performance measurement into a single all-in-one solution.
The system is built around a high-precision collimator working in conjunction with an electric target & light-source switch module and a target-surface monitoring device. A rhombic-prism expanded light path delivers large-aperture parallel beams simulating infinite-distance targets. The modular architecture allows rapid reconfiguration: bench-mounted for indoor pod calibration, heavy-tripod mounted for outdoor field trials, or paired with an arc moving platform for dynamic tracking and moving-target performance evaluation. Self-developed multi-optical-axis test software provides parameter input, real-time light-spot imaging, deviation calculation and test-result export.
