Fresnel Annular Zone Objective: a New Optical Element

A combination of a 32×32-element silicon-diode matrix and an Apple II computer is used to record and analyze Fabry–Perot interference ring patterns. The main advantage over conventional methods consists in the possibility of selecting the spectral resolution after registration and in the absence of alignment problems. Application of an image converter tube with VUV transmitting window in front of the matrix extends the applicability of the device to UV and VUV spectra.

A new type of Fabry-Perot spectrometer has been developed to achieve multichannel operation with recovery of the light that is lost in conventional systems. The light reflected from the interferometer is recycled in a predetermined way using small right angle prisms. When applied to nanosecond light pulses, the new system allows multichannel recording with a single detector. In this paper the realization of the instrument is presented. It has been tested in a prototype version with five channels. More than ten channels should be attainable. Some characteristic properties of the instrument are discussed.
