Opis:
In scanning microscope the cathode ray tube of high resolution is used. The screen of this tube is formed by raster consisting of 4096×4096 luminous elements, composing the image. This raster allows to form images of investigated microobject on the screen in a wide range without loss of resolution. The accuracy of imaging on the screen depends on the current setting errors in inductive coils of deflection system. The ways of reducing the static error of the current set in a voltage-current converter are proposed.

Opis:
The acceleration of the dynamic microobjects (MO) movement, the motion of which is accelerated uniformly or non-uniformly is an important task for television measuring systems. Most existing measuring systems usually have a small range of acceleration with a short period of growth. Such period of growth of the acceleration is characteristic for many dynamic MO. Better instruments to determine the non-uniform velocity of the various objects are based on various laser devices. These instruments are contactless and high-speed enough. In the paper the basics of the television scanning optical microscope (TSOM) are presented. In the Chapter 2 the schematic diagram of the TSOM and its main functionalities are pointed out. In the Chapter 3 an adaptation of the TSOM for movement acceleration of microobjects is discussed. Modified structural and functional diagram of the instrument is presented.

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.
