Abstract

The invention relates to a fiber array dynamic infrared scene generation apparatus based on a MEMS technology and belongs to a dynamic infrared scene generation technology field. By using the apparatus of the invention, conversion from a visible light image to an infrared image can be realized. Purposes of greatly increasing a performance index of the dynamic infrared image generation apparatus and reducing cost can be reached. The apparatus comprises: a substrate, a fiber array formed by pixel columns and a visible light absorption infrared radiation layer of a pixel column top. A substrate material can use transparent glasses or silicon according to different optical path designs. The fiber array is made on the substrate by using a MEMS technology. The pixel columns forming the fiber array are mutually independent and can be taken as an imaging unit. A visible light absorption infrared radiation film is made on the each pixel column top. The visible light absorption infrared radiation film absorbs energy of the incident visible light image, radiates outwards the infrared light after the temperature is increased and generates the infrared image corresponding to the visible light image.

Description

technical field [0001] The invention relates to an optical fiber array dynamic infrared scene generation device based on MEMS technology, and belongs to the technical field of dynamic infrared scene generation. Background technique [0002] Infrared scene generation technology is the core technology of the hardware-in-the-loop simulation system for infrared imaging guidance, and plays an important role in the simulation of the hardware-in-the-loop system for infrared imaging guidance technology. The dynamic infrared scene generation technology simulates the infrared radiation characteristics of the target and the background under laboratory conditions, and provides real-time infrared image sources of the infrared target and background for the tested infrared image sensor. [0003] Dynamic infrared image generation technology can be classified into two types: direct radiation type and radiation modulation type. [0004] For direct radiation image converters, the imaging pixe...
