Abstract

The invention belongs to the technical field of optical imaging, and provides a planar photoelectric detection system based on a super-lens array, and the system comprises a radial planar super-lens array which consists of a plurality of planar super-lenses sequentially arranged along an optical path, a photon integration loop, and an information processing module. The planar super-lens array is used for splitting incident light into a plurality of narrow-band light beams and focusing the narrow-band light beams; the photon integration loop is used for receiving incident light passing throughthe planar super-lens array and carrying out phase adjustment on the incident light to meet interference conditions; and the information processing module is used for restoring the image based on theinterference image generated by the photon integration loop to obtain a high-resolution image. The system does not need to use a large number of grating beam splitters for light splitting, the scale of a photon integration loop is reduced, the overall structure is compact, and the integration level is high; meanwhile, loss is reduced, and the energy utilization rate is high; furthermore, the sizeand the weight of the remote sensing load can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of optical imaging, in particular to a plane photoelectric detection system based on a metalens array. Background technique [0002] In many application fields such as astronomical observation and space remote sensing, in order to detect darker, smaller and farther targets, the requirements for the detection capabilities of space telescopes are also getting higher and higher. The continuous improvement of the spatial resolution of traditional telescopes has encountered technical and engineering bottlenecks, and it is difficult to continuously increase the spatial resolution of traditional direct imaging telescopes by increasing the aperture. In order to solve the above technical problems, those skilled in the art have developed a new photoelectric detection imaging technology based on the principle of interference, that is, Segmented Planar Imaging Detector for Electro-optical Reconnaissance (SPIDER). Curren...
