Abstract

An interferometer employing a 4f optical imaging system, through which both reference and sample beams are propagated, between diffraction gratings configured as input and output beam-splitting / beam-combining components. A Fourier-transform spectrometer utilizing the same and a microscope as an input optical sub-system. The interferometer includes a variable-phase-delay optical element in a Fourier plane of the imaging spectrometer defined between lens elements of the 4f optical system. In a special case, an additional 4f optical imaging system is used at the output of the interferometer, through which interferograms are registered at the detector. Light output collected by the detector has the same optical path difference between reference and sample beams at any point across field-of-view. A method for performing imaging spectrometry and forming images of an object under the microscope.
