This "Cited by" count includes citations to the following articles in Scholar. Recent advances in X-ray detector technology have resulted in the introduction of segmented detectors composed of many small detector modules tiled together to cover a large detection area. The main idea is to split n photons over m modes such that every mode has no more than one photon, which is detected alongside propagation by an APD.

The reflected beam of the micro- cantilever may undergo intensity and shape modifications prior to reaching the PSD. The spectrometer used in this study is capable of high resolution reciprocal linear dispersion of approximately 0.

Silicon PIN photodiodes consisting of 2 or 4 elements. A calorimeter designed for these algorithms must be finely segmented in order to reconstruct the showers constituting a jet. There is a delay in PSAPD signals that increases as the excitation position moves from the corner to the center of the device and the timing resolution concurrently worsens.

Such improvement substantially increases the detective quantum efficiency DQE , leading to the possibility Hyperspectral imaging solution expanded its reach to a large number of applications including precision agriculture, medical diagnostics, food sorting, machine vision, waste management etc. Si photodiode.
