Description
Technical Field
The invention belongs to the technical field of infrared imaging, and particularly relates to a non-refrigeration type medium-long wave dual-waveband infrared imaging device and method.
Background
With the progress of interference and stealth technology in battlefield environment, the single-band infrared imaging system has the defects of poor detection and identification capability on a target and high false alarm rate of an automatic early warning system in many application scenes. If the inherent and obvious difference and complementarity of the target in the medium-wave infrared band and the long-wave infrared band are utilized in the infrared imaging process, the rich dual-band information of the target is obtained, and the detection efficiency of the medium-wave and long-wave dual-band infrared imaging device can be effectively improved through the dual-band image fusion technology.
Currently, medium-long wave dual-band infrared imaging devices are mainly classified into three types:
in the first category, dual detector medium and long wave dual band imaging devices. Because the refrigeration type single-waveband infrared imaging core with the same area array size is about ten times of the price of the non-refrigeration type single-waveband infrared imaging core, the cost of the double-waveband infrared imaging device is increased rapidly because the refrigeration type infrared imaging core is adopted by the traditional medium-long wave double-waveband infrared imaging device.
And the second type is a double-line-array medium-long wave dual-band imaging device. Based on the manufacturing technology of the linear array detector, the detection linear arrays of two wave bands are arranged on the same focal plane in parallel, so that the linear array detector capable of detecting the radiation of the two wave bands is obtained, and the scheme is a scheme for reducing the cost and the difficulty; however, the imaging resolution is reduced due to the staggered distribution of the medium-long wave response pixels, and the cost is increased due to the adoption of the refrigeration type infrared detector.
And in the third category, the medium-long wave dual-band imaging device of the single detector. The single pixel simultaneously obtains medium-wave and long-wave infrared radiation, and has high imaging resolution, but compared with the single-band refrigeration type infrared detector process, the manufacturing process difficulty is extremely high, the cost is increased by more than three times, and therefore the cost of the medium-wave and long-wave dual-band infrared imaging device of the single detector is extremely high.
