The Measurement of Spatial and Temporal Distribution of Radiation, Using a Talbot Spectrometer.

Abstract

Our goal was to measure the distribution of radiation S as a function of its angular coordinates alpha, beta and its wavelength lamda. We first measured S(alpha), i.e. the distribution of radiation as a function of one angular coordinate. From this we learned how critical the various parameters of our instrument, such as collimation and the gratings substrate flatness, were to its successful operation. These investigations led to the design of new interferometric test instruments which include an autocollimator, and a lateral and radial shearing interferometer. Finally a theoretical study of an instrument to measure S(alpha, beta, lamda) was accomplished.
