Description

technical field [0001] The invention belongs to the technical field of infrared imaging detection, and more specifically relates to a liquid crystal-based electric modulation imaging spectrum array infrared detection chip. Background technique [0002] In general, light-frequency electromagnetic radiation originating from the Earth, the sun, stars, interfering or deceptive light sources constitutes the target's background light field. The differences in materials, components, energy states, structures, shapes, activities, and living environments of natural or artificial material structures make them exhibit different spontaneous emission and reflection, scattering, or transmission properties of external electromagnetic radiation, but all There is intrinsically labelable characteristic spectral electromagnetic information. They generally appear in the electromagnetic form of nano / subnanometer spectral width, distributed in the ultraviolet, visible, infrared and THz spectral ...

Problems solved by technology

However, the existing problems are still: the spectral imaging device based on the wide-spectrum detection device still needs to be equipped with complex and precise feeding, driving or scanning mechanisms, which are large in size and mass, slow in response, long in the generation and conversion of spectral images, and occupy electronic resources. Large volume, not suitable for high-speed carriers or targets, difficult to perform arbitrary imaging spectrum cut-in or jump
