SYSTEME D'IMAGERIE SPECTROMETRIQUE

The system has a camera (1) taking images e.g. infrared image, formed through an objective lens (2) on a matrix (3) of photodetectors. An interferential Fabry-perot device (4) has an axis forming a fixed angle with an optical axis of the lens. The fixed angle is greater than semi opening angle of an...

More Information
Summary:The system has a camera (1) taking images e.g. infrared image, formed through an objective lens (2) on a matrix (3) of photodetectors. An interferential Fabry-perot device (4) has an axis forming a fixed angle with an optical axis of the lens. The fixed angle is greater than semi opening angle of an input field corresponding to each image. The camera and the device are mounted on a mobile support (10) and fixed with respect to each other during a rotation of the support so that the images taken by the camera are formed from rays that traverses a space between plates of the device. An independent claim is also included for a method for detecting an object and obtaining spectral characteristic of the object.
