Abstract
A novel spectrometer concept is analyzed and experimentally
verified. The method relies on probing the speckle
displacement due to a change in the incident wavelength.
A rough surface is illuminated at an oblique angle, and
the peak position of the covariance between the speckle
patterns observed in the far field with the two wavelengths
reveals the wavelength change. A spectral resolution of
100 Mhz is argued to be achievable.
