Optical Measurement Accuracy in the Case of Non-classical Light
M. Schubert, Michael Fleischhauer · Journal of Modern Optics · 1990
The influence of optical elements on the statistical properties of the input radiation is analysed by quantum-theoretical means for a representative optical arrangement consisting of beam splitters as well as for various types of grating spectrometers. In particular non-classical light states are studied. Optimum conditions for the maintenance of the signal-to-noise ratio of sub-Poissonian input radiation are derived.
