AI Technical Summary
Technical Problem
Existing laser sensors cannot identify laser spectra within the solar spectrum, cannot simultaneously measure sunlight and lasers, and are large in size and weight.
Method used
Design a laser and solar detection composite sensor, which uses an incident mask, a top detector and a bottom detector. The incident mask achieves spectral attenuation and protection, the top detector absorbs sunlight and the bottom detector absorbs laser light, and they share a common incident light channel.
Benefits of technology
It enables simultaneous measurement of sunlight and laser light, reduces equipment size and weight, achieves multi-energy reuse, and lowers the overall satellite resource requirements.
