Position-sensitive detectors (PSDs) and corresponding measurement techniques have become essential components in modern scientific instrumentation. They translate spatial variations—often in the form ...

Advanced-technology sensors, coupled with data processing and fusion and networked communications, have enabled new approaches to warfighting and have been essential for reducing combat losses, ...

An immense advantage of EM 2 detectors is that—when calibrated properly—they are noiseless and single ion counting is possible. The essence of an EM is a serial connection of discrete metal plates ...

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: ...
