The laboratory of traffic facilities (LAVOC) is working in the fields of design, operation and maintenance of transport infrastructures. Since 1998 the LAVOC proposes an ITS course about the concepts and the methods of the transport telematics in order to ...
The intensity point spread function (IPSF) is most often used to characterize optical imaging systems. For some imaging applications such as digital holographic microscopy the 3D amplitude point spread function (APSF) more completely describes an optical s ...
The point spread function is widely used to characterize the three-dimensional imaging capabilities of an optical system. Usually, attention is paid only to the intensity point spread function, whereas the phase point spread function is most often neglecte ...
Due to the limited depth of field of brightfield microscopes, it is usually impossible to image thick specimens entirely in focus. By optically sectioning the specimen, the in-focus information at the specimen's surface can be acquired over a range of imag ...
The present thesis develops some specific aspects of digital holographic microscopy (DHM), namely the effect of shot noise on the phase image accuracy, the use of DHM in micro-tomography and in aberrations evaluation of a microscope objective (MO). DHM is ...
Recent developments in Digital Holographic Microscopy (DHM) have permitted to achieve imaging accuracies and resolutions down to the nano-range. This result could be obtained by careful control of all parameters involved in the wavefront reconstruction. ...
We have designed and realized a new integrated Hall structure that converts the magnetic field vector in the chip plane, into an ac signal, whose amplitude and phase correspond to the magnitude and direction of the field, respectively. It is the first Hall ...
Digital color, by its ambiguous nature, which always oscillates between a writing and a sensation, is always shifting, elusive, intangible, and yet, well presents, through the increasing use of computers in every field. Since it seems impossible to solve n ...
In this paper, we intend to gain an understanding of the interaction of light with microstructures. Measurements of amplitude and phase in the diffracted field close to gratings using a heterodyne scanning probe are presented. Coherent light diffracted by ...
A review, with refs. When mentioning prokaryotic metabolic engineering, most people will immediately think of Jay Bailey. Jay's contribution to this fast-growing field is evident and familiar to many. Therefore, instead of a detailed tech. review, we attem ...
