AI Technical Summary

Benefits of technology

This technology allows for precise measurements on both space and time dimensions at once by capturing three dimensional data from multiple angles simultaneously without any distortion or blurriness during image capture. It also provides accurate results even when there are slight variations between different images due to imperfections such as vibrations caused by movement over uneven surfaces.

Problems solved by technology

This patented technical problem addressed in this patents relates to combining both imaging techniques with complementary or alternative methods like coherence illumination and electrical/light reflection technique to improve image quality while reducing costs associated with these processes.

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 , a hyperspectral full-polarization detection device for interferometric light field imaging of the present invention, comprising a sequentially configured pre-optical telescopic system 1, a transverse shear interference system 2, a light field imaging system 3, an area array detector 4 and a signal processing system 5. The detected target light passes through the front optical telescopic system 1, the transverse shear interference system 2, and the light field imaging system 3 in sequence, and reaches the area array detector 4, and the signal processing system 5 obtains the band from the area array detector 4. The interference image with polarization information is processed to obtain the two-dimensional space image, hyperspectral information and full Stokes polarization component of the detected target.

Abstract

The invention discloses a high-light-spectrum full-polarization detection device for interference light field imaging, comprising a prepositioned optical telescoping system, a transverse cutting interference system, a light field imaging system, an area array detector and a signal processing system, which are arranged in sequence, wherein light of a target to be detected sequentially passes through the prepositioned optical telescoping system, the transverse cutting interference system and the light field imaging system to reach to the area array detector; and the signal processing system is used for extracting a two-dimensional space image, high-light-spectrum information and a full-Strokes polarization component of the target to be detected from the area array detector. With the adoption of the detection device, light strength information of a target two-dimensional space, the full-Strokes polarization component of each point of the target, and high-resolution-ratio light spectrum information of each point of the target can be obtained by one time of measurement; and the detection device has a simple structure.
