Abstract

The invention discloses a radiation conversion sheet, a radiation plane array detector and a radiation scanning stitch image detection system of the radiation plane array detector. The radiation conversion sheet is mainly and technical characterized by comprising a substrate, an array grid, absorbing nanometer powder and upper conversion material nanometer powder, wherein a layer of the absorbing nanometer powder and a layer of the upper conversion material nanometer powder are sequentially and uniformly filled on the bottoms of each grid through hole of the array grid so as to form a conversion unit, the radiation conversion sheet absorbs target radiation energy, the radiation wave band is from ultraviolet radiation to far infrared radiation and microwave radiation, the temperature of the absorbing nanometer powder is increased, the emitted infrared radiation is absorbed by the upper conversion material nanometer powder, and visible light is emitted. According to the radiation plane array detector, the array grid of the radiation conversion sheet is closely attached to the detection surface of the visible light detector. The radiation scanning stitch image detection system contains a drive platform for making the radiation image be scanned in the radiation plane array detector. According to the present invention, the characteristic, the direction, the distance and the speed of the target radiation are obtained through the airspace-time domain resolution of the target radiation scanning stitch image.

Problems solved by technology

[0006] Traditional remote sensing and telemetry (microwave radar, photoelectric radar) systems use wavelength (long) intervals and time intervals to develop reconnaissance systems in segments to improve the signal-to-noise ratio of target signals, and use the difference between target infrared sweep images and noise features to increase Target information extraction rate, remote sensing telemetry system based on the above mechanism, (1) the system is huge and complex; (2) corresponding detection systems need to be opened for different reconnaissance environments, the operator's judgment on the reconnaissance environment and the detector switching cycle, The difficulty of coordination is increased; (3) the backscattering of emitted laser light and the electromagnetic radiation of laser power supply interfere with each detection system; (4) the existing infrared detectors have a narrow response band, large pixel size and small number of pixels (compared to CCD detection device comparison)
