Title: METHOD FOR EXTENDING THE SPECTRAL RANGE OF AN INTEGRAL DIGITAL HOLOGRAPHIC NANOSPECTROMETER
Abstract:
A method for doubling the spectral range at the output end of an optical waveguide of a spectral digital nanospectrometer, which method consists in that the spectrometer is provided with a polarizing splitter, which is mounted in the light path from a laser source to a planar optical waveguide, as a result of which the radiation being investigated is split into the components TE and TM. The split components are then spatially separated with the aid of a digital planar hologram by distances which are equivalent to the separation of output channels by half a period for the case of unseparated polarization.
