Enhanced backscattering of partially coherent light

Optics Letters, 1996
The backscattering enhancement of light from random media is analyzed for situations in which the scatterers are illuminated with spatially partially coherent light. The effect of coherence is incorporated into the existing theories by use of the angular correlation description for the illuminating light field. When the area of illumination is infinite,

Lensless imaging with partially coherent light

Optics Letters, 2007
Based on the fourth-order correlation of light, lensless imaging with incoherent or partially coherent light is investigated theoretically by use of classical optical coherence theory. A novel lensless optical system for implementing imaging is proposed.

Isotropic bicomponent partially polarized and partially coherent light

Optics Letters, 2014
The degree of coherence of scalar light remains constant when the fields are modified by the same random linear transformation, which can be represented by the multiplication by a random complex number. This shows that the coherence properties of scalar light at order two are not modified with the increase of disorder of each field that results from ...

Focusing of partially coherent light

Frontiers in Optics 2007/Laser Science XXIII/Organic Materials and Devices for Displays and Energy Conversion, 2007
We investigate the focusing of partially coherent light and show that for certain types of correlation functions the intensity distribution can exhibit a local minimum at the geometrical focus.

Holography in partially coherent light

Optics Communications, 1980
Abstract A Michelson interferometer has been used to obtain good holographic carrierfringes of the order of 200 to 300 fringes/ mm over an area of 1 cm × 1.5 cm with a Hg-are source and extended aperture with and without filter. The fringes have been used to record holograms.

Properties of Partially Coherent Light*

Journal of the Optical Society of America, 1966
The traditional classical theory of coherence is discussed with particular emphasis on the distinction between narrowband coherent and incoherent sources. The significance of this difference is discussed in terms of conventional classical optics experiments.

Twisting partially coherent light

Optics Letters, 2018
Twisted Gaussian Schell-model beams were introduced 25 years ago as a celebrated example of a "genuinely two-dimensional" partially coherent wavefield. Today, a definite answer about the effect that a twist phase should produce on an arbitrary cross-spectral density has not yet been reached. In the present Letter, the necessary and sufficient condition
