INTERFEROMETRY DEVICE FOR FOURIER TRANSFORM MULTIPLEX SPECTRO-IMAGING APPARATUS AND SPECTRO-IMAGING APPARATUS CONTAINING THE SAME

摘要

An interferometry device for Fourier transform multiplex spectrometric imaging designed to move relative to an object-zone according to a direction of motion constituting a reference direction for said interferometry device. The device includes a prismatic block of transparent material having a first and a second input/output face meeting in a block edge, a semitransparent plate inside said block, and first and second reflective surfaces forming a roof and arranged facing respectively the first and the second input/output face via the semitransparent plate. The device further has at least one slanted dioptrical separation surface with a dioptry angle ( alpha ) provided between one of the input/output faces and the corresponding reflective surface, and the deviation of the angles of inclination ( beta , beta ') of the first and second rooflike reflective surfaces relative to the corresponding input/output face is non-zero.
