We report on holographic recording of nanosecond events on a conventional CCD camera. Three frames of an air-discharge event, with resolution of 5.9 ns and frame interval of 12 ns, are recorded in a single CCD frame. Each individual frame is reconstructed by digital filtering of the CCD frame, since successively recorded holograms are centered at different carrier frequencies in the spatial fre...

We describe a new 4096×4096 pixel CCD mosaic camera (MOCAM) available at the prime focus of the Canada-France-Hawaii Telescope (CFHT). The camera is a mosaic of four 2048×2048 Loral frontside-illuminated CCDs with 15 µm pixels, providing a field of view of 14 ′ ×14 ′ at a scale of 0 ′′ .21 pixel −1. MOCAM is equipped with B, V, R and I filters and has demonstrated image quality of 0 ′′ .5–0 ′′ ...

A new method for combining small-sized areal array CCD sensors to make one wide-angled digital aerial photography system is studied in this paper. The method is to install several small-sized areal array CCD cameras in the way that their perspective projecting centers form a line or a square, with their principal optical axes slanting fixed angle along designed directions. Such installation aim...

Performance characteristics of various readout systems coupled to an EGG-AVO streak camera were analyzed and compared to scaling estimates. The purpose of the work was to determine the limits of the streak camera performance and the optimal fielding conditions for the Amador Valley Operations(AV0) streak camera systems. We measured streak camera limitations in spatial resolution and sensitivity...

Mirage effect is contactless and non destructive method which has been used a lot to determine thermal properties of different  kind of samples , transverse photothermal deflection PTD in  skimming configuration with ccd camera  and special programs is used to determine thermal conductivity of porous silicon ps  film.

Compared with conventional camera, the light field camera takes the advantage of being capable of recording the direction and intensity information of each ray projected onto the CCD (charge couple device) sensor simultaneously. In this paper, a novel method is proposed for reconstructing three-dimensional (3-D) temperature field of a flame based on a single light field camera. A radiative imag...
