Abstract

The invention discloses a shortwave infrared image detection device adopting an up-conversion luminescent material, and belongs to the technical field of infrared imaging. The conventional shortwave infrared image detection device is complex in structure, high in cost and low in response speed, and has noise interference. According to the shortwave infrared image detection device adopting the up-conversion luminescent material provided by the invention, an imaging lens is positioned in front of a photodetector; a photodetector drive unit, an image storage unit and an imaging processing unit in a field programmable gate array (FPGA) master control chip are connected with the photodetector; the imaging processing unit is also connected with the image storage unit and a communication interface; the imaging lens is a visible light imaging lens; the photodetector is a visible photodetector; and an up-conversion luminescent material plate is positioned in front of the visible light imaging lens. The shortwave infrared image detection device adopting the up-conversion luminescent material is used for acquiring shortwave infrared images.

Description

technical field [0001] The invention relates to a short-wave infrared image detection device using an up-conversion luminescent material, which is used for collecting short-wave infrared images and belongs to the technical field of infrared imaging. Background technique [0002] Short-wave infrared (1-2.5 μm) imaging equipment is widely used in military fields such as night vision, detection and surveillance, remote sensing, fire control systems, infrared imaging guidance, and photoelectric countermeasures. Imaging equipment is rarely used, and its demand is quite large; in the civil field, short-wave infrared imaging systems are widely used in fire protection, electric power, construction, security and other fields. In my country, the application of infrared imaging equipment in these industries is still in its infancy , the technology is relatively scarce, but the development space is huge. [0003] Short-wave infrared imaging equipment has a short-wave infrared imager. In...
