Patent attributes
A LIDAR imaging system (90) includes: an illumination source block (100) having at least one illumination source (110) for emitting at least one polarized illumination beam (20) of first polarization with wavelengths in a first wave length range (21); an optical engine core (200) having a first polarized beam splitter panel (210); a quarter wave retarder panel (230) configured between the external image object (900) and the optical engine core (200); and a first imaging block (300) having a plurality of first illumination detectors (310). The imaging system is more compact and ensures optical alignment between the radiation sources and the detectors. Moreover, the polarized illumination beams and the retarded reflection beams do not interfere with each other though transiting along the same axis, thus improving the imaging quality of the imaging system.
