The beam of light is intercepted by another polarizer (analyzer in this case) set at 90° to the plane of polarization.
In addition, many police officers carry first-aid kits and other medical equipment, such as a defibrillator, in their patrol cars; they also may carry a portable breath analyzer for testing drivers who may be intoxicated.
The analyzer can be rotated to obtain maximum contrast in the image, and so the direction of polarization of the light transmitted through the object can be determined.
Most mass spectrometers have four major components: an inlet system, an ion source, a mass analyzer, and a detector.
Another milestone in the development of the modern analog computer was the invention of the so-called differential analyzer in the early 1930s by Vannevar Bush, an American electrical engineer, and his colleagues.
An accelerator suffers from this defect to an even greater degree, and large quantities of "trash" ions are found at the expected analyzer location of the cosmogenic isotope.
The particle accelerators used in nuclear physics can be viewed as mass spectrometers of rather distorted forms, but the three principal elements the ion source, analyzer, and detector are always present.
The properties that render low pressures desirable include a reduction in the scattering of the beam in the analyzer, which causes interfering background effects and a reduction in the production of spurious beams out of the residual gases, particularly from the organic compounds that are present.
A colour video analyzer reads the red, blue, and green records of the tests over a range of six f-stops to establish "printer lights".
At first they represented quantities with mechanical components (see differential analyzer and integrator), but after World War II voltages were used; by the 1960s digital computers had largely replaced them.
