A new infrared interferometer at 10 microns and its applications
Abstract
The paper describes the design and principle of operation of an infrared interferometer utilizing a 10.6-micron frequency-stabilized CO2 laser as a source. The interferometer is designed for monitoring the homogeneity of optical materials and for inspecting the waveform generated by an optical system. The instrument has the following characteristics: a precision of lambda/4, an analysis time of 5 s, a resolution of 128 x 128 points, and a capacity in the transmission range of materials of 10 to 100 per cent.
