Abstract:
A multi-slit spectrometer comprising:a multi-slit structure defining a plurality of parallel thin slits;a first optical structure for directing object light onto said multi-slit structure;a light dispersing element;an optical collimating device for collimating and directing light which has passed through said slits of said multi-slit structure onto said light dispersing element;an optical focusing structure for focusing light which has passed through said light dispersing element at an image plane; anda two-dimensional detector array disposed at said image planewherein said detector array comprises a plurality of detector elements having a width dimension in a direction transverse to a direction in which the slits extend, and wherein said slits are separated by a distance equal to an integral multiple of said width dimension, wherein said integral multiple is equal to MN+1 of NM-1, where M is the number of slits and N is an integer.
