Filling Factor and Signal‐to‐Noise Ratios in Optical Interferometric Arrays [PDF]
Publications of the Astronomical Society of the Pacific, 1999 Signal-to-noise ratios are derived for an interferometric array of N diffraction-limited optical/IR telescopes with a Fizeau-type beam recombination. We consider two types of objects—extended sources and point sources—and three sources of noise—signal photon noise, sky background noise, and detector noise.

Signal-to-noise ratio in optical photodiode receivers [PDF]
Proceedings of the IEEE, 1974 The SNR of a frequency-compensated optical receiver is derived, and the validity of the assumptions used in the derivation is analyzed. A compensating circuit having a wide range of application in video receivers is suggested.

Mechanism for improving the signal-to-noise ratio in scanning optical microscopes [PDF]
Optics Letters, 1996 We demonstrate an improved signal-to-noise ratio in a scanning optical microscope used to read out information from a magneto-optical data storage layer. By placing a shading band in the return path of the optical system we can reduce noise by as much as 3 dB in certain spatial frequency ranges.

Optical signal-to-noise ratio measurement by optical homodyne tomography
Optics Letters, 2006An all-fiber optical homodyne tomography setup is introduced that measures the optical signal-to-noise ratio through reconstruction of the photon statistics. The scheme described has been conceived for applications to optical communications. In particular, the signal-to-noise ratio has been evaluated at lambda= 1.55 microm as a function of the received
