The electrical-modulation imaging-spectrum liquid crystal module comprises a plurality of electrical-modulation imaging-spectral liquid crystal structural units, voltage signals and wavelengths, the electrical-modulation imaging-spectrum liquid crystal module is in array distribution and used for allowing a target wave beam to generate multistage second-highest reflection interference, the voltage signals are uploaded in the electrical-modulation imaging-spectral liquid crystal structural units by independent adjustment, and the wavelengths are used for modulating spectrum infrared lightwaves penetrating the electrical-modulation imaging-spectral liquid crystal structural units; the area-array uncooled infrared detector is used for converting spectrum infrared lightwaves penetrating the electrical-modulation imaging-spectrum liquid crystal module into electrical signals; the displacement control preprocessing module is used for subjecting the photoelectric signals to quantization, rectification and non-uniformity correction to obtain target infrared image data. By the infrared detection chip, adjustable rapid spectrum registration, spectrum search, spectrum gaze, spectrum tracking or spectrum lock can be realized; the chip is easy to couple with optical, photoelectrical and mechanical structures and good in environmental adaption.

Description

technical field [0001] The invention belongs to the technical field of infrared imaging detection, and more specifically relates to an addressable electrically adjustable imaging spectrum infrared detection chip. Background technique [0002] Under normal circumstances, the material structure in nature has a markable fingerprint electromagnetic radiation energy spectrum, which is often presented in the form of optical frequency electromagnetic radiation with a nanometer / picometer spectral width. What appears in the field of view of the imaging system is this Targets and scenes with different spectral radiation characteristics. Based on the property of relatively stable spectral radiation characteristics to capture local targets in complex background environments, the targets can be highlighted intuitively through optical hardware, which will effectively reduce the amount of information processing, save electronic resources, and significantly improve the electronic image cons...
