Description

technical field [0001] The invention relates to the technical field of photoelectric detection, in particular to an optical path device capable of integrating detection and control of light intensity. Background technique [0002] In information technology, photoelectric sensing technology is an extremely important sensing technology. At present, the light source related to photoelectric detection is controlled by the light source power of a specific wavelength and specific band, and the light intensity detection is also independent. The unit price of a system is relatively high, and the existing multi-band detection is often used to measure the full-band spectral transmittance and reflectance of materials, and there is still a shortage in the integration of multi-band continuous optical power detection and regulation. [0003] The current optical device needs to be equipped with an independent light intensity detection system for detection, and it cannot realize effective d...
