Abstract
A high-admittance local suppression highlight imaging system includes a first optical zoom lens having a plurality of lenses, inclusive of at least three aspheric lenses, to thereby function as an imaging system; a second optical zoom lens including a plurality of lenses symmetrically arranged to thereby function as a relay system; a polarizing beam splitter disposed between the first optical zoom lens and the second optical zoom lens; a LCoS disposed at an imaging point at an end of the first optical zoom lens; and a photosensitive component provided in form of a CCD or a CMOS and disposed at an imaging point at an end of the second optical zoom lens. Therefore, the imaging system features enhanced admittance of light, ensures that images captured during a nocturnal picture-taking process will be clear but not overexposed, and is applicable to nocturnal vehicle surveillance and the other safety detection systems.
