Abstract

The invention discloses an uncooled optical readout type infrared thermal imaging system. The system comprises a front-end structure, an excitation light source and a rear-end structure which are sequentially arranged from front to back, wherein the front end structure comprises a vacuum cavity, and a lens, an infrared detection array, a sample table and a rearview mirror which are sequentially arranged in the vacuum cavity from front to back; the central positions of the lens, the infrared detection array, the sample table and the rearview mirror are located on the same straight line; the infrared detection array comprises a plurality of detection units, and each detection unit comprises a supporting structure, a temperature-sensitive light-emitting layer, a reflecting layer, an absorbinglayer and a silicon micro lens which are sequentially arranged from bottom to top. The technical problems that an existing infrared imaging system is complex in structure and preparation process andhigh in cost are solved.

Description

technical field [0001] The invention relates to the technical field of infrared imaging, in particular to an uncooled optical readout infrared thermal imaging system. Background technique [0002] Any object in nature can emit infrared radiation when the temperature is higher than absolute zero. Infrared radiation refers to electromagnetic waves with a wavelength range of 0.75-1000 μm, also known as thermal radiation or infrared rays. Infrared thermal imaging is a non-contact, non-invasive, fast and efficient technology. By detecting infrared radiation and measuring the intensity of infrared radiation, humans can detect infrared bands. Infrared thermal imaging technology is often used in military reconnaissance, In the fields of satellite and aircraft remote sensing, it is often used in production quality inspection, medical diagnosis, vehicle night vision system and security monitoring in daily life. [0003] Infrared imaging systems can be divided into photoelectric detec...
