Description

technical field [0001] The present invention relates to the technical field of charge-coupled devices, in particular to a monolithic hybrid CCD structure. Background technique [0002] CCD (Charge Coupled Device) refers to a charge-coupled device, which is a detection element that uses the amount of charge to represent the size of the signal and transmits the signal by coupling. It is the core component of the aerospace camera, but the aerospace camera usually needs to meet the requirements of a large dynamic range. , the slope of the output linear part of the existing CCD is small, and its dynamic range is usually suitable for the environment with high brightness. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a single-chip hybrid CCD structure that can take into account imaging at night, morning and evening and daytime. [0004] In order to solve the above problems, the present invention provides a monolithic ...

[0002] CCD (Charge Coupled Device) refers to a charge-coupled device. It is a detection element that uses the charge to represent the signal size and transmits the signal by coupling. It is the core component of the aerospace camera, but the aerospace camera usually needs to meet the requirements of a large dynamic range. , the slope of the output linear part of the existing CCD is small, and its dynamic range is usually suitable for environments with high brightness. Therefore, the existing CCDs are usually difficult to take into account the requirements of large dynamic range imaging at night, morning and evening, and daytime.
