Wave-front-dividing array interferometers without moving parts for real-time spectroscopy from the IR to the UV

Interferometers of the Michelson or Mach-Zehnder type are designed as array interferometers. The number of array channels is equal to the number of points needed for an interferogram for Fourier transformation.

Description
Summary:Interferometers of the Michelson or Mach-Zehnder type are designed as array interferometers. The number of array channels is equal to the number of points needed for an interferogram for Fourier transformation. Similarly one may use an array of step gratings with each grating having a different step height and producing one point of the interferogram. These interferometers, which do not have moving parts, use all the incident light, and the interferogram is instantly produced for real-time spectroscopy.
