SMALL-SPOT SPECTROMETRY INSTRUMENT WITH REDUCED POLARIZATION |
摘要 |
A small-spot imaging, spectrometry instrument (Fig. 1) for measuring properties of a sample (27) has a polarization-scrambling element, such as a Lyot depolarizer (19), incorporatied between the polarization-introducing components of the system, such as the beamsplitter (17), and the microscope objective (21) of the system. The Lyot depolarizer varies polarization with wavelength. Sinusoidal perturbation in the resulting measured spectrum can be removed by data processing techniques or, if the depolarizer is thick or highly birefringent,l may be narrower than the wavelength resolution of the instrument.
