Single acquisition polarisation imaging with digital holography
René Salathé, Christian Depeursinge, Etienne Cuche, Guy Delacrétaz
A demonstration of the ability of digital holography to image and to measure spatial variations of the polarisation of an object wave with a single image acquisition is presented. This is achieved by recording a hologram with two reference beams presenting ...
1999Application of a 3-CCD color camera for colorimetric and densitometric measurements
Video cameras have been used in the graphic arts industry primarily for quality inspection applications where one is interested only in the macro or large scale appearance defects of the print i.e. acceptable/not acceptable. CCD video cameras also have the ...
SPIE-Int. Soc. Opt. Eng1998Optical tomography at the microscopic scale by means of a numerical low coherence holographic technique
Christian Depeursinge, Etienne Cuche
We describe here a numerical application of the optical low- coherence holographic microscopy (OLCHM) technique. A low coherent source illuminates an object and the backscattered light interfere with a reference wave which optical path's length can be prec ...
SPIE1996Performances of endoscopic holography with a multicore optical fiber
A holographic setup that involves the use of a multicore optical fiber as an in situ recording medium has been developed. The hologram is transmitted to a CCD camera for electronic processing, and the image is reconstructed numerically, providing more flex ...
1995Endoscopic holography with a muticore optical fiber applied to biomedical imaging
An in situ holographic technique based on the use of a flexible miniaturized endoscope (diameter less than 1 mm) was developed for medical applications. The holographic system features a multicore optical fiber (MCF) coupled to a CCD camera to record the h ...
