Image intensifier or Flouroscope, is a highly complex piece of equipment which uses x-rays and produces a 'live' image feed which is displayed on a TV screen.It allows low energy x-rays to be amplified through the machine resulting in a smaller dose to the patient. It consists of an x-ray source, input window, input phosphor, photocathode, vacuum and electron optics, output phosphor and output window. It allows for lower x-ray doses to be used on patients by magnifying the intensity produced in the output image, enabling the viewer to easily see the structure of the object being imaged. Components of Image intensifier are: C-arm (encompasses the actual X-ray source and Image intensifier), table, radiographic exposure and program controls post processing software viewing monitors. There are two types of image intensifier. They are classified into two types namely fixed image intensifier and mobile image intensifier. Fixed image intensifier are used in most x-ray departments as 'screening rooms'. The types of investigations for which this machine can be used for is vast. Examples include: barium studies, endoscopy studies (ERCP), fertility studies (HSG), angiography studies (Peripheral, Central and Cerebral), therapeutic studies. Mobile image intensifier is smaller in design than a fixed image intensifier.

An image storage device comprising an A/D converter for converting an analog image signal transmitted from a high resolution TV camera into a digital image signal to be stored, a D/A converter to which the stored digital image signal is output after being read out and by which the output digital image signal is converted to an analog image signal to be output to a TV monitor, the device having a plurality of memories for storing a digital signal input as a high resolution image and converted by A/D converter in parallel in time series, a controller for controlling the image signal stored in each memory corresponding to the frame frequency of a receiver to be used at a time lag of one frame, and a selector for outputting the digital image signal read out of each memory to the D/A converter by selecting the image depending on the select signal of said controller .

Laser have a very narrow beam which allows the mapping of physical features with very high resolution compared with radar. In addition, many chemical compounds interact more strongly at visible wavelengths than at microwaves, resulting in a stronger image of these materials. Suitable combinations of lasers can allow for remote mapping of atmospheric contents by looking for wavelength-dependent changes in the intensity of the returned signal. Laser imaging systems can be divided into scanning systems and non-scanning systems. The scanning system can again be divided into sub-groups by the way the laser beam is scanned across the object. Beam-scanners scan a narrow beam, typically in lines on top of each other, therefore this type of system is called a Laser Line Scanner (LLS). Fan-beam scanners scan a fan-shape beam across the object
