Self-common phase on-chip interference spectrum imaging method

Abstract

A self-common phase on-chip interference spectrum imaging method comprises the following steps: S1, determining lens array distribution according to a lens array usefulness function; S2, enabling lenses to make primary phase adjustment for incident lights through a dielectric wetting effect or integral body deformations; S3, enabling the primarily phase adjusted incident lights to form baseline pairs through a photon integration chip, and accurately adjusting phases of the base line pairs so as to form interferences, thus forming interference images; S4, extracting information of the interference images; S5, using a photon interference image reconstruction method to obtain a target digital image and a spectrum image according to the interference image information.

[0002] my country's future deep space exploration project will implement four major tasks. The Mars probe will carry out scientific research on material composition, Mars structure, and Mars environment. To complete these scientific tasks, the Mars probe must be equipped with spectral imaging with high efficiency, light weight, and small size. , a new type of detection payload with low power consumption, if the traditional spectral imaging system is used, the volume, quality and power consumption will not be greatly reduced to meet the needs of deep space detection

[0003] The volume of payloads that can be carried by deep space exploration satellites is limited, and each payload must meet the requirements of the satellite's overall loading position and volume. The traditional spectral imaging payload is an integral system composed of multiple optical components, and its shape cannot be changed arbitrarily. It has certain limitations in adapting to the overall requirements of deep space exploration satellites

[0004] At the same time, in emergencies such as sudden wars and terrorist attacks, the existing aerospace reconnaissance system does not have the ability to quickly revisit and quasi-real-time reconnaissance and surveillance of specific areas, resulting in insufficient battlefield situation data acquisition and untimely intelligence information support.

Moreover, once the satellite is destroyed during wartime, the existing aerospace imaging system has a long development cycle and high cost, and will not be able to meet the demand for real-time supplementary payloads in military warfare
