ABSTRACT:
An arrangement for sensing the wavelength shift of light from a polychromatic light source features a tilted concave holographic reflection grating that diffracts light from the light source and disperses the light across the focal plane of the arrangement. A pair of matched detectors disposed behind the focal plane senses the light transmitted by a variable neutral density filter at the focal plane. The difference in output signal electrical currents generated by the detectors is a measurement of the shift in polychromatic wavelength distribution.
