Electronic imaging system

Existing electronic imaging systems currently used for high energy inspection applications are often based on the combination of the following elements ... 

A versatile Laser-SNMS instrument consists of a versatile microfocus ion gun, a sputtering ion gun, a liquid metal ion gun, a pulsed flood electron gun, a resonant laser system consisting of a pulsed Nd YAG laser pumping two dye lasers, a non-resonant laser system consisting of a high-power excimer or Nd YAG laser, a computer-controlled high-resolution sample manipulator on which samples can be cooled or heated, a video and electron imaging system, a vacuum lock for sample introduction, and a TOF mass spectrometer.

Field frequency The rate at which images in an electronic imaging system are presented. In conventional terrestrial television (National Televison Systems Committee (NTSC)), two fields are presented to make up one frame (a complete picture). 

Scintillators are also used in the detectors of CT scanners. Here an electronic detector, the photomultiplier tube, is used to produce an electrical signal from the visible and ultraviolet light photons. These imaging systems typically need fast scintillators with a high efficiency. 

Collecting optics, radiation detectors and some form of indicator are the basic elements of an industrial infrared instrument. The optical system collects radiant energy and focuses it upon a detector, which converts it into an electrical signal. The instrument s electronics amplifies the output signal and process it into a form which can be displayed. There are three general types of instruments that can be used for predictive maintenance infrared thermometers or spot radiometers line scanners and imaging systems. 

The technique employs a beam of swift (-500kV) electrons grazing the surface of interest. Provided that the beam is accurately aligned along a crystal zone axis, and that the electron-optical imaging system is adequate, then images are obtained which appear to show the atomic surface structure in profile (see Figure 1). 

FLIM systems can be purchased as an add-on for a standard fluorescence microscope. Such a system will consist of a CCD camera coupled to a modulatable image intensifier, an LED light source, and driver electronics. This system will modulate the LED and image intensifier while shifting the phase between them as it takes a series of images (Fig. 2.1).
