Title:
INFRARED DETECTION CHIP AND INFRARED DETECTOR
Document Type and Number:
WIPO Patent Application WO/2023/016453
Kind Code:
A1
Abstract:
An infrared detection chip (100) and an infrared detector. The infrared detection chip (100) comprises an optical component (10), an infrared detection array (20), and a photoelectric readout module (30). The infrared detection array (20) comprises a plurality of infrared detection units (21) arranged in an array. The infrared detection units (21) can emit visible light under the effect of excitation light and can also have their temperature changed under the effect of infrared radiation to change the intensity of the visible light. The intensity of the visible light is negatively correlated with the temperature of the infrared detection units (21), and the temperature of the infrared detection units (21) is positively correlated with the intensity of the received infrared radiation. Photoelectric readout units (31) of the photoelectric readout module (30) have one-to-one correspondence to the infrared detection units (21), and the photoelectric readout units (31) are configured to detect the intensity of the visible light emitted by the infrared detection units (21) and convert same into an electrical signal.
