A serious effort has been made in developing accurate and efficient bidirectional goniophotometric devices for detailed studies of Complex Fenestration Systems, capable of measuring BTDFs and/or BRDFs in an appropriate way. The existing instruments are alm ...
In this thesis new imaging approaches for optical microscopy are proposed and studied. They are based on the use of dynamic structured illumination in combination with a demodulation detection concept employing CMOS image detectors. Two particular implemen ...
We present a virtual digital camera sensor, whose aim is to simulate a real (physical) image capturing sensor.To accomplish this task, the virtual sensor operates in two steps. First, it accepts a physical description of agiven scene and simulates the enti ...
Four years ago [1] we assessed the status of CMOS imaging for high-speed applications. We also gave an outlook of the near future in high-speed imaging In this paper we revisit the topic of high speed imaging in a slightly different angle and make the poin ...

Digital video-based luminance mapping systems require the establishment of a precise relation between the considered spatial referential and the associated pixel coordinates on the image. Such a relation may vary with the measurement conditions, and an adj ...
This paper describes a new co-processor architecture designed for CMOS sensor imaging. The co-processor unit is integrated into the image acquisition loop so as to exploit the full potential of CMOS selective access imaging technology. The processing featu ...
A new fully integrated two-stage operational transconductance amplifier-capacitor (OTA-C) sine oscillator circuit configuration using a 0.5 μm CMOS digital process is described. A simple linear impedance analysis is presented to predict the amplitude and d ...
Visual capabilities recovery for some kind of illness is possible through subretinal implantable device stimulation. Two possible approaches for retinal pixel are proposed, fabricated in 0.35mum CMOS, tested and compared including electronic response on a ...
The paper presents an original analog-to-digital converter (ADC) array meeting the constraining requirements in resolution, speed, size, and low power consumption of high-performance low-cost video cameras. The converter array is based on ADC cells relying ...
This paper presents a low-power analog simulator for the transient stability of a two-machine power system. The simulator is implemented in a standard digital CMOS process. Its building blocks are: sine shaper, transconductor with extended linear range, an ...
