Mantis shrimp eye-simulated multi-channel real-time and multi-spectrum polarization imaging detection device

Abstract

The invention provides a mantis shrimp eye-simulated multi-channel real-time and multi-spectrum polarization imaging detection device and belongs to the technical field of target optical detection. Existing detection equipment is loose in structure, large in size and poor in use flexibility. According to the technical scheme of the invention, a signal detection part and a signal converting and processing part are connected through optical fiber bundles. The array units of a focused imaging array, a spectrum polarization array, a positioning and coupling array, a positioning and outputting array and a photoelectric conversion array are the same in both number and arrangement mode, and are corresponding to one another in position front and back. Each array unit on the front surface of a substrate of the spectrum polarization array is plated with a spectral filter membrane, and each array unit on the back surface of the substrate is coated with a gold nano-rod polarization coating. In each polarization coating, a 0-degree polarization channel, a 45-degree polarization channel, a 90-degree polarization channel and a 135-degree polarization channel are distributed in the shape of the Chinese character Tian. The target polarization image of each spectrum lambda i collected by the photoelectric conversion array is transferred to the same computer, and then the computer divides the target polarization image of each spectrum lambda i into four equal parts in the shape of the Chinese character Tian. In this way, the polarization images of a target in each spectrum lambda i in the light transmitting directions of 0 degrees, 45 degrees, 90 degrees and 135 degrees can be obtained.

Description

technical field [0001] The invention relates to a multi-channel real-time multi-spectral polarization imaging detection device imitating mantis shrimp eyes, which belongs to the technical field of target optical detection. Background technique [0002] The reflected light on the surface of objects in nature has its own spectral characteristics and polarization characteristics. As far as detection is concerned, the polarization information of the target, such as polarization angle and polarization degree, becomes effective information reflecting the target. The eyes of mantis shrimps have a complex structure, consisting of thousands of small eyes, which are divided into three regions: ventral, dorsal and middle frequency bands. Mantis shrimp eyes can efficiently and accurately identify polarized light, because different ommatidia are sensitive to polarized light in different directions, which produces antagonism. The ventral and dorsal ommatidia were sensitive to polarized ...
