Description

technical field [0001] The invention relates to a detection method and device for devices with tracking and variable beam divergence angle pointing functions, belonging to the technical field of mechanical engineering. Background technique [0002] The infrared tracking and beacon light pointing function device provides the host with 5 beacon lights with a beam divergence angle of 1° and a maximum distance of 2 meters and a parallelism better than 0.3°. The device mainly completes the capture and stabilization of the host under airborne conditions Track and aim, after the host is successfully tracked, it emits active-pointing beacon lights to provide a set of (5) real-time active-pointing beacon lights for the host. [0003] The solution needs to meet the tracking under all-day conditions. The device needs to have infrared tracking function and 5-way beacon light pointing function. There are strict requirements on the parallelism of the 5-way beacon light. The beam angle of ...
