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

Optics.org speaks to researchers in Sweden who have developed 1D and 2D position sensitive detectors as well as a compact and cost-effective spectrometer. Combining a position-sensitive detector (PSD) ...

The world of laser scanning microscopy is quickly evolving, thanks to the advent of fast and compact detector arrays. These arrays replace the typical single-element detector of traditional confocal ...

You’re undoubtedly familiar with the clip-on blood oxygen sensor and meter that uses a pair of LEDs and a photosensor. This non-intrusive transmissive-light device—which took decades to develop, ...

The detector array consists of plastic scintillator detectors, quadrant silicon detectors (QSD), double-sided silicon detectors (DSSD) and high-purity germanium (HPGe) detectors. Exotic nuclei near ...

InGaAs detectors have paved the way for near-infrared detection in industrial applications. Bob Grietens of XenICs describes the latest advances in InGaAs NIR camera technology. Commercially available ...

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: ...
