K008 streak & single frame camera

 

Application:    

The camera 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 streak and single-frame modes of recorded image. Record of the image from a streak tube screen is made by means of CCD readout unit with image input in the personal computer. Software provides the user with wide possibilities of processing the recorded image. 

Article [28] in "Publications" section is devoted to designing of this camera, articles [34-43, 45, 46, 54, 57-64, 83] - to its application.

Possible fields of application: 
  • ballistics;
  • combustion, detonation and explosion;
  • shock waves physics;
  • laser physics;
  • nonlinear optics;
  • nonstationary spectroscopy;
  • nuclear physics;
  • plasma physics including thermonuclear synthesis;
  • electrical breakdowns and discharges including lightning;
  • ecology (a register in LIDAR systems for detection and determination of air or water pollution’s  location, size and chemical composition), etc.
The main components of the camera: 
  • input objective (a set of the objectives is available);
  • mechanical shutter;
  • PV-201 time-analyzing streak tube 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;
  • three replaceable control units for millisecond, microsecond and nanosecond sweeps and the same frame durations;
  • RU-05M CCD readout system (1392x1032 pixels, 12-digit ADC, linear dynamic range ≥ 300) with an electrical (≤ 5 m) orfiber-optic (≤ 500 m) communicational line with the computer;
  • notebook with installed software;
  • three replaceable splits of  0.05, 0.1 and 0.2 mm width, which are setting closely with the photocathode's fiber-optic disk;
  • frame test-object (a standard SOI № 4 target) and slit test-object, which are setting closely with the photocathode’s fiber-optic disk for control of a spatial resolution;
  • neutral filter of 0.5, 1 and 2 density set on the input objective or its site;
  • holding plate for mechanical fixation of the camera on a work site.
