As three-chip hybrids, the amplifiers have from the start been designed to solve economically the problems that up to now have limited the use of off-the-shelf units. Key to keeping costs down is a capacitive-coupling approach to isolation. Any amplifiers so far available with the same capabilities are costly, enlisting magnetic or optical techniques to bridge the high-voltage barrier. Whether ...

Circular dynamic stereoscopy (CDS) has special advantages as it enables a 3-D measurement using a single CCD camera without a cumbersome setting. Annular streaks are recorded using this system and the size of annular streaks directly concerns to the depth from the CCD camera. That is, the size of annular streaks is inversely proportional to the depth from the CCD camera and the three-dimensiona...

The CLF own and use a variety of high dynamic range CCD cameras that are used for a variety of measurements on many of the experiments performed at the facility. The performance and characteristics of these cameras are of utmost importance when choosing which camera to use in any particular circumstance. Therefore, a calibration to determine the dynamic range and threshold sensitivity of the ca...

Acquiring the initial value of all profile of the object is essential for the integration of metrical data. It is described a new smart approach to acquire the initial value of all profile of the object in this paper, which is only to compute the calibration parameters of CCD camera and the projector in every angle, but not to do the complicated coordinate conversion. In the origin position the...
