What is a Power Spectral Density (PSD)? How is it different than an autopower? A Power Spectral Density (PSD) is the measure of signal's power content versus frequency. A PSD is typically used to characterize broadband random signals. The amplitude of the PSD is normalized by the spectral...
In absorbance spectroscopy (also known as absorption spectroscopy), an optical spectrometer measures the amount of light absorbed by a sample as a function of wavelength. This can provide important information about a samples molecular structure, concentration or optoelectronic properties. Depending on the...
It is based on measuring the phase shift of a light beam which travels through a layer structure so it possesses high sensitivity, and the phase angle measurement does not depend on the absolute intensity of light. Spectral information about the sample can be obtained by utilizing white light s...
Simple preparation—no DNA cleanup is required (as opposed to sequencing) Easy data analysis—genetic analysis software simplifies data analysis Independent method—does not require knowledge of the sequence of the fragment Relative quantitation information—from peak ...
Unlike an infrared filter, a low-pass filter operates on high-frequency spatial information, whereas an infrared filter removes spectral information. To put it simply, the optical low pass filter slightly blurs out the image before it reaches the silicon sensor. In an age where camera reviews ...
hyperspectral imaging involves capturing a broad range of wavelengths across the electromagnetic spectrum, beyond what human eyes can see. unlike traditional imaging, which records color information in three bands (red, green, blue), hyperspectral imaging captures hundreds of narrow spectral bands. this...
The SP detector from Leica Microsystems denotes a compound detection unit for point scanning microscopes, in particular confocal microscopes. The SP detector splits light into up to 5 spectral bands. The bands are independent and continuously tunable wit

Compared with NRZ signals, PAM4 signals have an additional two levels. This means that, under the sam...
EVEN IN this age of fast-developing information technology, public meetings still have a valuable role to play. Because I am nervous that this may not always be the case, I am glad to report that my recent experience is positive. The British Board of Film Classification (of which I am pr...
