Application:
The camera with
totally computer control is intended for registration of images of
fast running processes in a near infra-red and visible spectral range
and measurements of their spatially-temporal parameters in a multiple
9-frame mode of sweep of a recorded image.
Image recording from image converter tube (ICT) screen is carried out
with the help of high-speed (up to 1kHz) readout unit based on a CMOS
TV sensor with built-in buffer memory in volume 8 GB. Thus maximum
numbers of frames recorded by camera is ≥ 3x104
and maximum frame frequency is 9 kHz. In one 9-frame cycle the
maximum frame frequency is 5 MHz.
Software provides the user with wide
possibilities of processing the recorded image
The
subjects of high-speed multiframing cameras are reflected
in
articles

"Publications" section.
Possible fields of
application:
- ballistics;
- combustion,
detonation and explosion;
- shock waves
physics;
- nuclear physics;
- plasma physics including
thermonuclear synthesis;
- electric
breakdowns and
discharges including lightning.
The main components of the camera:
- input objective
(a set of the objectives is
possible) ;
- electromechanical
shutter;
- PIM-112 time-analyzing ICT with S-20
photocathode applied on a fiber-optic
disk, two pairs of deflecting plates, one microchannel plate (MCP) and phosphor screen
applied on a fiber-optic
disk;
- power supply
unit;
- control unit
totally programmed by a computer;
- RU-08 high-speed CMOS
readout unit (up to
1 kHz frame
frequency, 1280x1024 pixels, 8 or 12-digit ADC, 8 gigabyte buffer
memory space,
linear dynamic range ≥ 1000) with an electrical (≤ 5 m) or fiber-optic, 500 m communicational
computer link ;
- notebook with
installed software;
- neutral filter
of 0.5, 1 and 2 density set on the
input objective or its site;
- frame window
located closely to the photocathode's
fiber-optic disk and limiting frame's field dimensions;
- frame's
test-object is setting closely to cathode's
fiber-optic disk for control of a spatial resolution;
- fixing plate
for mechanical fixation of the camera on
a work site (or option – tripod).
