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...
Therefore, we examined the influence of three biological characteristics on the relationship between spectral and taxonomic diversity: vegetation density, spatial species turnover and invasion by non鈥恘ative species. We aimed to understand when and why spectral diversity may serve as an indicator of ...
Spectral devices are instruments that can accurately measure, identify, and quantify the specific characteristics of colors contained in light from a source. From this data, they can produce a Spectrum. Fig 1 Spectrum of Incandescent and LED lights.What...
However, actual analysis is extremely difficult because of the huge number of permutations that must be analyzed, and because the amplitudes must also be computed to see if spurs are large enough to actually interfere with system operation. Until now, this computation has been attempted using custo...
To perform fragment analysis on a CE system, primers must be designed that flank the region of interest. Fluorescent dyes are attached to the primers, and the fragments are amplified by PCR before electrophoresis. To prepare for capillary electrophoresis, a spectral calibration with the ...
There are many reasons you might select a spectral line. It might be because that line has exceptional intensity characteristics at low concentrations. It might be that it exhibits excellent linearity at higher concentrations. You might encounter many interferences in one material and none in another...
Static Spectrophotometer:Static spectrophotometers are usually used in laboratory or factory environments. They have high accuracy and stability and are suitable for measuring large quantities of samples. They are mostly desktop devices suitable for fixed position measurements. ...
Multispectral images can be displayed as natural color and color infrared if the bands are available. Pixels represent a location on the ground In addition to its spectral characteristics, a pixel represents a ground location. The figure below illustrates the relationship between the physical pixel in...

Camera lenses vary in optical quality. Two important specifications in any vision system are the sensitivity and the resolution of the lens, which have the following characteristics: Sensitivityis the ability of a machine to see in dim light or to detect weak impulses at invisiblewavelengths. ...
