Abstract
A spectra generator having an electrically programmable diffraction grating. There may be a broad band light source that emits light which is diffracted by the grating. Diffracting elements in the grating may be individually adjustable so that generation of a specific spectrum or spectra may be achieved. The diffracting elements may be adjusted according to electrical signals of a program from a computer. The generated synthetic spectra may be used for testing and calibration of spectrometers or other devices. Synthetic spectra may also be used for scene generation and other purposes.
Claims14
An apparatus comprising:
- a diffracting mechanism having a plurality of adjustable elements, the adjustable elements have set positions to provide certain spectra upon impingement of radiation on the diffracting mechanism;
- and
- a spectrometer configured to calibrate and/or test based on the certain spectra.
A broadband generator comprising:
- a light source;
- and
- a light diffracting mechanism, having adjustable elements, proximate to the light source, the elements are adjusted to diffract light from the light source as a specific spectrum or spectra;
- and
- a spectrometer configured to calibrate and/or test based on the certain spectra.
A method for generating spectra, comprising:
- providing radiation;
- and
- adjustably diffracting the radiation into spectra;
- conveying the spectra to a spectrometer;
- and
- testing the spectrometer to see if it appropriately detects the spectra.
