photomultiplier tube - Opis:
- Scanning television optical microscope is designed to investigate microscopic objects, larger than 0.1 micrometers. To illuminate microobject with this microscope there is used a high resolution cathode ray tube. Low illumination of the tested microobject lets to explore living microorganisms in real time. The current microscopic image has low contrast. To increase image contrast it is necessary to increase microscope sensitivity. The main sources of noise in scanning television optical microscope are: 1) composite video shaper; 2) photomultiplier tube; and 3) scanning cathode ray tube. Detailed analysis of noise sources in video signal of the microscope is presented in the paper. Equations describing the sources are given. Dependencies are plotted and discussed.
