We review two techniques of unconventional holography, coherence holography and photon-correlation holography, which we recently proposed and experimentally demonstrated. We will emphasize the importance of noticing mathematical analogies in optics and physical phenomena, which give insights into the methodology for developing new techniques.

Speckle statistics in optical coherence tomography and speckle reduction by frequency compounding
Optical Coherence Tomography and Coherence Techniques, 2003In this paper we are investigating the possibility of a frequency compounding method for speckle reduction in optical coherence tomography. The method is based on incoherent summation of the magnitudes of two independent interferometric signals, which were recorded at two different center wavelengths simultaneously.

Coherence and photon statistics for optical fields generated by Poisson random emissions
Physical Review A, 1983We examine the coherence properties and photon statistics of stationary light obtained by the superposition of nonstationary emissions occurring at random times, in accordance with a homogeneous Poisson point process. The individual emissions are assumed to be in a coherent, chaotic, or $n$ state. The statistical nature of the emission times results in

Theory of photon statistics and optical coherence in a multiple-scattering random-laser medium
Physical Review E, 2004We derive the photon-number probability distribution and the resulting degree of second-order optical coherence for light emission from a uniformly distributed active species within a multiple-light-scattering medium. This is obtained from a master equation describing the probability distribution for photons in the vicinity of position r, traveling ...

Optical and Quantum Electronics, 1982
The distinction between coherent and incoherent nonlinear optical interactions is established at the beginning of the paper. In the first part parametric up conversion (PUC) by coherent nonlinear optical mixing of the strong pumping radiation with weak input radiation is treated with respect to statistical properties of generating radiations.

Abstract A model of photon statistics and quantum phase distribution is analyzed for coherent optical communication links in the presence of quantum phase noise, dispersion and phase noise of the radio-frequency (RF) oscillator using an in-line optical amplifier. The quantum analysis of a dual drive Mach–Zehnder modulator and the quantum

Optical Coherence and Counting Statistics
1991The coherence of a light field can be domonstrated by the phenomenon of interference. In the classical experiment of Thomas Young in 1801 the coherence was induced by arranging that the light diffracted by a fine slit should illuminate two parallel slits which then acted as two coherent sources. In the more modern version of the experiment a laser beam

Optics Letters, 2013
The spatial stationarity of scattered optical fields constitutes a basic premise of coherence holography and photon correlation holography. Nevertheless, spatial stationarity seems to have attracted less attention and still remains a less familiar concept than temporal stationarity because it has been a common practice in statistical optics to assume ...
