Imaging detecting chip capable of adjusting polarization and spectrum and preparation method thereof

Abstract

The invention discloses an imaging detecting chip capable of adjusting polarization and spectrum. The imaging detecting chip comprises an electric modulation polarization module, an electric modulation spectrum module, and a photosensitive array that are arranged in parallel from top to bottom and have the completely same light-transmitting areas. The electric modulation polarization module includes an electric modulation polarization pattern electrode lead layer, a first substrate, an electric modulation polarization pattern electrode, a first liquid crystal orientation layer, first liquid crystal layer, a second substrate, and an optical medium layer that are arranged in parallel from top to bottom. The electric modulation spectrum module includes a third substrate, a first electric modulation spectrum electrode, a second liquid crystal orientation layer, a third liquid crystal orientation layer, a second electric modulation spectrum electrode, and a fourth substrate that are arranged in parallel from top to bottom. Therefore, technical problems that the application range is limited, the energy utilization rate is low, and the detection performance is affected by the grating according to the existing polarization imaging detection technology as well as a technical problem that the spectral polarization light detection can not be realized by the existing spectral light imagingdetection technology are solved.
