AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
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 ...
New methods and apparatus for authenticating security documents such as banknotes, passports, etc. which may be printed on any support, including transparent synthetic materials and traditional opaque materials such as paper. The invention is based on moir ...
In the course of 1998, the Spectromicroscopy beamline at ELETTRA completed commissioning and succeeded in performing its first test experiments. The beamline is designed to perform photoemission experiments with high spatial resolution, which is obtained b ...
Optical coherence domain reflectometry is applied here to the study of diffusive biological tissue. This non-contact technique allows us to probe the light reflected at a tissue interface, and the back scattered light through the tissue thickness, with ver ...
We present a digital method for holographic microscopy involving a CCD camera as a recording device. Off-axis holograms recorded with a magnified image of microscopic objects are numerically reconstructed in amplitude and phase by calculation of scalar dif ...
In health care practice, diagnosis and therapy tasks are founded on the analysis of medical images. Traditionally, such analysis was performed using optical devices like light boxes or microscopes installed in clinical rooms or laboratories. In the last de ...
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 ...
We describe a new fluorescence imaging device for clinical cancer photodetection in hollow organs in which the image contrast is derived from the fluorescence lifetime of the fluorochrome at each point in a 2D image. Lifetime images are created from a seri ...
