Data analysis is aimed at extracting meaningful information from the hy- perspectral data. A limited number of image analysis algorithms have been developed to exploit the extensive information contained in hyperspectral im- agery for many different applications such as mineral mapping, military target...
Spectral information about the sample can be obtained by utilizing white light sources and monochromators. The ratio of the complex Fresnel reflection coefficients are measured by ellipsometry. It can be divided to an amplitude term as it is a complex number, and a phase shift term, which corres...
Spectrometers are the most prevalent type of spectral device. Optical spectrometers can be used to study how light interacts with, or is emitted by, a sample. This is known as optical spectroscopy (or spectrometry). The name 'optical spectrometer' is a broad term, as there are a number of...
Machine vision is sometimes conflated with the termcomputer vision. The technology is often integrated with artificial intelligence (AI), machine learning anddeep learningto accelerate image processing. How does machine vision work? Machine vision uses cameras to capture visual information from the surrou...
OFDMA enables the LTE downlink to transmit data from a base station to multiple users at higher data rates than 3G, with improved spectral efficiency. Single-carrier FDMA is used for the uplink signal, which reduces the transmit power required of the mobile terminal. ...

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
To prepare for capillary electrophoresis, a spectral calibration with the corresponding matrix standard for the selected group of dyes must be performed on the genetic analyzer in order to accurately detect the dye-labeled primers. Each unknown sample is mixed with the size standard and formami...
Edinburgh Instruments’ RM5 Raman Microscope is designed for analytic and research purposes. The truly confocal design is unique to the market and offers uncompromised spectral resolution, spatial resolution, and sensitivity. The RM5 builds on the expertise of robust and proven building blocks, combine...
Feature extraction: The first step is to extract useful audio features from the input audio and ignore noise and other irrelevant information. Mel Frequency Cepstral Coefficient (MFCC) techniques capture audio spectral features in a spectrogram or mel spectrogram. Acoustic Model: Spectrograms are passed...
