Streak cameras are used to study the x-rays that are emitted from Inertial Confinement Fusion (ICF) targets as they implode. These cameras operate by using a photocathode to convert the x-ray flux to a secondary electron current. Secondary electrons are then focused onto a phosphor screen using the streak tube electron optics, and finally recorded using a charged coupled device (CCD) camera. Th...

The accurate measurement of the position of celestial objects is a fundamental step for several astrophysical investigations. For ground based instruments, the atmosphere is considered the basic limiting factor; in space, the knowledge of the instrumental parameters and/or of their stability define the performance limits, but CCD cameras operated in time delay integration may take advantage of ...

We use a charge coupled device ~CCD! camera and a multi-tau software correlator to measure dynamic light scattering ~DLS! at many angles simultaneously, from 0.07° to 5.1°. Real-time autocorrelation functions are calculated by averaging both over time and over CCD pixels, each corresponding to a different coherence area. In order to cover the wide spectrum of decay times associated with the lar...

Positioning is one of the most important operations in color sorting systems for falling grain which directly affects the performance of these systems. Linescan Charge Coupled Device (CCD) image sensor is widely used in the color sorting systems, however, the processing algorithms are much complex. In this paper, a complete set of algorithms is presented for the above systems. First, the Line-S...

A dedicated simulator, Poisson_CCD, has been constructed which models astronomical CCDs by solving Poisson's equation numerically and simulating charge transport within the CCD. The potentials free carrier densities CCD are self-consistently solved for, giving realistic results for distribution storage wells. simulator used to model being construct LSST digital camera. output validated comparin...

In mobile robotics, the ability to acquire three-dimensional information from an environment and to have color information about surrounding objects makes the robot vision system more suitable for complex tasks such as environment modeling. We present a simple 3-D color-range scanner CRS, which is able to capture the geometry and color of the measured object. The CRS utilizes a scanning laser s...

We discuss the joint calibration of novel 3D range cameras based on the time-of-flight principle with the Photonic Mixing Device (PMD) and standard 2D CCD cameras. Due to the small field-of-view (fov) and low pixel resolution, PMD-cameras are difficult to calibrate with traditional calibration methods. In addition, the 3D range data contains systematic errors that need to be compensated. Theref...

The paper presents a metric investigation of the Fuji FinePix Real 3D W1 stereo photo-camera. The stereo-camera uses a synchronized Twin Lens-CCD System to acquire simultaneously two images using two Fujinon 3x optical zoom lenses arranged in an aluminum die-cast frame integrated in a very compact body. The nominal baseline is 77 mm and the resolution of the each CCD is 10 megapixels. Given the...

The work presented here describes a method that allows three component velocity measurements to be made, quickly and non-intrusively, across a plane in a flow defined by a laser light sheet. The method, two frequency planar Doppler Velocimetry (2ν-PDV) is a modification of the Planar Doppler Velocimetry (PDV) technique, using only a single CCD camera, and sequential illumination of the flow usi...
