Harmonically matched grating-based full-field quantitative high-resolution phase microscope for observing dynamics of transparent biological samples [PDF]
, 2007 We have developed a full-field high resolution quantitative phase imaging technique for observing dynamics of transparent biological samples. By using a harmonically matched diffraction grating pair (600 and 1200 lines/mm), we were able to obtain non ...

Measurement of the pure dissolution rate constant of a mineral in water
, 2008 We present here a methodology, using holographic interferometry, enabling to measure the pure surface reaction rate constant of the dissolution of a mineral in water, unambiguously free from the influence of mass transport.

Experimental investigation of temperature fields in a synthetic jet
MATEC Web of Conferences, 2014 The paper deals with the measurement of temperature fields in a synthetic jet. This type of experiment presents several challenges; therefore, to ensure the best precision possible, two experimental methods were used – digital holographic interferometry (

Aero-optical characterization of aircraft optical turrets by holography, interferometry and shadowgraph [PDF]
, 1980 Density variations in the aircraft boundary layer, turret wakes and shock waves create distortion of an optical wavefront through associated refractive index variations. Such effects can be observed directly through optical flow visualization.

Rainbow holographic interferometry [PDF]
Optics Communications, 1978 Abstract A one-step rainbow holographic process is applied to holographic interferometry. Experimental demonstrations of double exposure and time-average interferograms are included. Comparison is made with the conventional holographic process. We found that the rainbow process provides better equality and less speckle noise.
