Abstract
A low cost spectral camera may include a multiple Fabry-Perot cavity filter with silicon photodetectors distributed one beside another in a two-dimensional matrix fashion. Each cavity may be designed to capture a pixel from an image. The two-dimensional fabry-perot array may function as a sensor to capture an image in spectral form. Spectral information may be obtained to generate spectral displays.
Claims20
A two-dimensional spectral camera, comprising:
- a plurality of spectrophotometers;
- a controller;
- and
- a sampling circuit,
- wherein the plurality of spectrophotometers receives incident light reflected from a target, and the controller controls the sampling circuit to sample spectral information from the received light to generate image data.
A method of capturing spectral data using a two-dimensional spectral camera, the spectral camera including a plurality of spectrophotometers and a sampling circuit, the method comprising:
- receiving incident light reflected from a target using the plurality of spectrophotometers;
- sampling spectral information from the received light using the sampling circuit;
