The study of the illumination MS 45 (vol. 1), preserved in library Corpus Christi College Cambridge, has made it possible to attribute his illustrative apparatus hand illuminator from Toulouse, active around middle fourteenth century, designated as Master Avignon Decretum for having illuminated ms. 659 Municipal Library Avignon, containing precisely text Gratiani

A two -dimensional non-observable square array illuminator using four polarized beams from two interferometers in tandem is reported. The array pattern could be scanned over large longitudinal distances without loss of distortion. Fringe visibility of interferograms has been studied as a function of polarization of the interfering beams. The expressions for the array patterns and the fringe vis...

The target tracking using multistatic passive radar in a digital audio/video broadcast (DAB/DVB) network with illuminators of opportunity faces two main challenges: the first challenge is that one has to solve the measurement-to-illuminator association ambiguity in addition to the conventional association ambiguity between the measurements and targets, which introduces a significantly complex t...

Increasing daylighting levels contributes to improving the energy efficiency of buildings and consequently fight against climate change. This work presents a new illuminator based on previous single-axis polar heliostat. heliostat allows redirecting sunlight specific space be illuminated at any time day. The system presented is simple but compact in size. It has been manufactured by 3D printing...

Appropriate monochromatic illumination that is spatially uniform will ensure densitometry of stained polyacrylamide electrophoresis gels with high sensitivity and repeatability. The approach of using an array of LEDs as an illuminator has practical limitations. Here we describe an alternative method based on adapted liquid crystal display backlighting. By changing the fluorescent light source a...

Synthetic aperture radar systems operating with satellites in geosynchronous orbits (GEO-SAR) can provide a permanent coverage of wide specific areas the Earth’s surface. As well as for primary applications remote sensing such soil moisture and deformation monitoring, availability signal emitted by GEO-SAR on regional scale makes it an appealing illuminator opportunity bistatic radars. Differen...
