The detector array consists of plastic scintillator detectors, quadrant silicon detectors (QSD), double-sided silicon detectors (DSSD) and high-purity germanium (HPGe) detectors. Credit must be given ...
The UL 02 15 2 amorphous silicon infrared detector can be used in thermography and industrial applications and has a 160 120-pixel-array format. Its thermal time constant is less than 7 msec. It has a ...
Precisely measuring the parameters of a laser beam is crucial to using it successfully. Allen Cary of Photon Inc describes the range of beam profiling techniques available. Most applications for ...
A new X-ray detector prototype could dramatically reduce the radiation exposure and its associated health risks for healthcare workers and patients, at the same time boosting the resolution of medical ...
The significance of the entrance slit and the diffraction grating in forming a spectral image of the incident light in the image plane is discussed in the articles “An Introduction to a Spectrometer: ...
