This practical course includes a set of tasks and laboratory works oriented
at students of the third to the fourth year of he GPWP Chair, students of the
third to the fifth years of the Radio Physics Division, and attendees of the
ILC Graduate Courses.
 All
the laboratory works and most of the tasks of this course are automated through
the use of IBM PC/Pentium/486 computers. 21 computers and 2 network printers
of this laboratory are linked into a local network, providing the possibility
to operate as a part of the network of he Building of Nonlinear Optics. The
architecture of data acquisition and control systems systems and laboratory
works employs various types of plug-in boards, CAMAC modules, GPIB boards, original
connecting cards and virtual generators, breadboard modules, and sound blasters,
which are used as generators of analog signals of different shapes and as analog-to-digital
converters. This laboratory also employs video cameras with frame grabbers for
inputting an image into a computer. Windows'95 is used as the basis operation
system. Experimental studies and data processing procedures are LabView-automated.
Pascal and C++ are employed to program the different blocks of data acquisition
and control systems systems.
Several tasks are based on analog-digital computational complexes, including
the AVK-31 analog-computational machine (employed to model the processes under
study), computer (to control the analog-computational machine, process the data
coming from this machine, as well as display these data and visualize the modeling
processes), and adapter boards.
This practical course includes laboratory works along the following directions:
Data acquisition and control of experiments
programming elements of the data acquisition and control systems on the basis
of the ISA bus under LabView with the use of various plug-in boards;
elements of the development and application of CAMAC-based data acquisition
and control systems under LabView;
programming a CAMAC controller using Turbo Pascal and C++;
programming data acquisition and control systems in a CAMAC standard using
high-level languages;
programming a PC-ADC10 adapter board for transferring the experimental data
using Turbo Pascal and C++;
programming elements of the data acquisition and control systems in the IBM
PC standard using Turbo Pascal and C++;
principles of data acquisition and control in the CAMAC system.
Laser measurements
laser interferometric vibration sensor;
automated laser Doppler anemometer;
studying the methods of detection of optical radiation using a photodiode.
 Analysis
of random processes
digital processing of experimental results (fundamentals of correlation,
spectral, and wavelet analysis);
studying correlation properties of noise;
studying spectral properties and correlation characteristics of random processes;
studying the random action on oscillation and self-oscillation systems;
modeling the generation of classical squeezed states of electromagnetic field
(studying the random-force action on a parametric amplifier);
