K017 multiframe camera

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 [13, 14, 19, 34, 37, 41, 45, 49-52, 56, 58, 61, 63, 80] in "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).
