Optical design method and solutions of linear-in-k spectrometers exhibiting extremely low residual nonlinearity
Background A spectrometer is an optical instrument used to measure the intensity of light by wavelength, or wavenumber (k). A conventional spectrometer has intrinsic nonlinearity in k over the pixels due to the nonlinear angular dispersion in k corresponding to the grating or prism used. For spectrometers used in spectral domain optical coherence tomography...
