Wide-range high-sensitivity multi-mode composite detection imaging optical system
By designing a wide-area, high-sensitivity, multi-mode composite detection and imaging optical system, and using a combination of a primary reflector and various optical mirrors, modular synchronous imaging of the three optical subsystems was achieved. This solved the problems of low integration and reduced field of view in the optical system, and improved imaging quality and detection performance.

AI Technical Summary
Existing optical systems have low integration and their field of view is reduced for the same detector size, which cannot meet the requirements of multi-band high-sensitivity detection and high-resolution imaging under a large field of view.
Design a wide-area, high-sensitivity, multi-mode composite detection and imaging optical system. The system uses a combination of a primary reflector, multiple spectral beam splitters, a folding mirror, and a zoom objective lens. The system uses a large-aperture primary reflector shared by the three bands to split the light into mid-wave infrared and visible/short-wave paths. The second spectral beam splitter further splits the light into visible and short-wave infrared paths, thus achieving synchronous imaging of the three optical subsystems.
It achieves modular and integrated design of three optical subsystems, adapts to high-resolution detectors above 1K, expands the field of view, reduces the complexity and assembly difficulty of the optical system, improves imaging quality and detection performance, and meets the requirements of large field of view, high sensitivity detection and high-resolution imaging.
