Abstract

The invention discloses a large-diameter infrared super-lens camera, belonging to the technical field of infrared imaging and micro-nano photonics, comprising a large-diameter super-lens, an infrared focal plane array detector, a super-lens mechanical assembly and a casing, The aperture is greater than 50mm, the thickness is less than 2mm, and the distance between the large-diameter superlens and the infrared focal plane array detector is greater than 30mm; the superlens mechanical assembly adopts a buffer structure to fix, adjust and shock the superlens; Sealed to protect the lens from heat and water. The invention adopts strict electromagnetic field value, diffraction design algorithm and large-area semiconductor process preparation method to increase the aperture of the superlens to more than 50mm, and greatly improves the focal length and The magnification overcomes the problems of short focal length, small magnification and insufficient imaging distance of the previous metalens camera, and can detect and image medium and long distance objects.

Description

technical field [0001] The invention belongs to the technical field of infrared imaging and micro-nano photonics, and more particularly, relates to a large-diameter infrared superlens camera. Background technique [0002] Infrared imaging technology is a technology that obtains the thermal radiation information of the target object and converts it into an image visible to the human eye. Compared with visible light imaging technology, this imaging technology has the advantages of strong concealment, strong anti-interference ability, and good environmental adaptability. Therefore, it is widely used in military fields such as night reconnaissance, infrared guidance, missile warning, and security monitoring, vehicle night vision, and industrial detection. and other civil fields. [0003] In recent years, with the increasing application of infrared imaging technology in airborne, mobile and other occasions sensitive to the weight, volume and cost of equipment, light, compact and...
