IMAGING SYSTEM BASED ON FABRY-PEROT CAVITY

摘要

An imaging system based on a Fabry-Perot cavity. The system comprises a monochromatic imaging chip, and a bandpass filter and a Fabry-Perot cavity, which are arranged in an upstream optical path of the monochromatic imaging chip, wherein the bandpass filter and the Fabry-Perot cavity are separate elements, and the bandpass filter is configured to have a first optical response range from 430 nm to 760 nm, and the Fabry-Perot cavity is tunable such that an optical response peak thereof can be within the first optical response range or completely beyond the first optical response range. By using a tunable Fabry-Perot cavity covered by a wide spectrum and a bandpass filter with a first optical response range from 430 nm to 760 nm, and by means of a monochromatic imaging chip, an imaging system for RGB imaging, IR imaging and ON-OFF imaging can be realized, and a spectral image of any waveband can be parsed.
