SENSOR ARRAY SPECTROMETER

An optical system is disclosed and includes an optical sensor, a plurality of photosensitive pixels disposed on the optical sensor, a wavelength-selective optical filter in optical communication with the photosensitive pixels, the wavelength-selective optical filter being disposed remotely from the optical sensor, an area disposed in the wavelength-selective optical filter, the area having a transmission spectrum different from a transmission spectrum of a portion of the wavelength-selective optical filter not in the area and a reflector, the wavelength-selective optical filter and a measurement subject each being disposed between the reflector and the optical sensor along an optical path. 本发明公开了一种光学系统并且该光学系统包括：光学传感器；多个感光像素，该多个感光像素设置在该光学传感器上；波长选择性光学滤光器，该波长选择性光学滤光器与该感光像素光学连通，该波长选择性光学滤光器远离该光学传感器设置；区域，该区域设置在该波长选择性光学滤光器中，该区域的透射光谱与该波长选择性光学滤光器的不在该区域中的部分的透射光谱不同；和反射器，该波长选择性光学滤光器和测量对象各自沿着光学路径设置在该反射器和该光学传感器之间。
