Session 1pNS: Noise 1pNS5. On near-field acoustical inverse measurements of partially coherent sources

The sources of jet noise have been investigated through the use of near-field array measurements. An understanding of spatial coherence properties in the jet near field leads to insight about source composition. A metric called coherence length is a useful tool for summarizing near-field coherence information. Near-field coherence lengths are presented in this work for a full-scale jet, which s...

Off-axis setup taking full advantage of incoherent illumination in coherence-controlled holographic microscope.

Coherence-controlled holographic microscope (CCHM) combines off-axis holography and an achromatic grating interferometer allowing for the use of light sources of arbitrary degree of temporal and spatial coherence. This results in coherence gating and strong suppression of coherent noise and parasitic interferences enabling CCHM to reach high phase measurement accuracy and imaging quality. The a...

General theorem of spatial coherence: application to three-dimensional imaging

The Michelson stellar interferometer1 (MSI) (also known as long-baseline interferometer) is used for measuring the shape of planar objects that emit quasi-monochromatic, spatially incoherent light. Its principle of operation is based on recording interference patterns in the far field obtained by a two-pinhole Young interference configuration. The fringes’ visibility and phase versus the separa...

High-speed wide-field coherence-gated imaging via photorefractive holography with photorefractive multiple quantum well devices

The parallel pixel acquisition inherent in wide-field coherence-gated imaging techniques offers the possibility of high-frame-rate imaging and volumetric imaging, including through scattering media. We discuss photorefractive holography using sensitive, dynamic photorefractive multiple quantum well (PRQW) films as a promising approach and, after reviewing the factors that determine the sensitiv...

Grating-enhanced Coherent Imaging

We describe a coherent imaging technique that utilizes a diffraction grating placed near the object to alias high spatial frequency information through the imaging system pupil. The resulting optical field in the image plane is detected by means of digital holography. Multiple measurements are taken with the grating shifted by a fraction of its period between exposures. Linear signal processing...
