The counting ADC technique (see Figure 6.70) basically uses a sampling pulse to take a sample of the analog signal, set an R/S flip-flop, and simultaneously start a controlled ramp voltage. The ramp voltage is compared with the input, and when they are equal, a pulse is generated which resets the R/S flip-flop. The output of the flip-flop is a In this paper Makhlouf, Perronet, Dupuis Levêque-Fort and Dubois introduce, in a very elegant way, a method to simultaneously acquire morphological information offered by Optical Coherence Microscopy (OCM) and Fluorescent Microscopy (FM).

2010-09-15В В· While coherence gate curvature can be largely ignored in low-NA systems, it is notably problematic for high-NA systems and phase-sensitive techniques. OCM is an imaging technique that uses coherence gating to perform optical sectioning [ 3 ], and frequently augments the spatial confocal gating in confocal microscopy. Optical coherence microscopy (OCM) is capable of imaging the backscattering potential of a sample with high transversal and axial resolution. We report on a combination of OCM with a differential phase-contrast technique that permits imaging of the subwavelength optical path differences that occur between a narrow beam probing a sample and its surrounding.
