RU-07 CCD readout unit



    The unit is intended for record and digital processing of continuous and pulse images from an image converter streak and frame cameras’ output as well as of images that appear at arbitrary time moments. In principle, it can be used for work with a wide class of the optical images supplied to its input by means of fiber or lens optics

Basic components: 

  • CCD television camera (TVC) with a fiber-optic input, equipped with a rotating ring for  azimuthal alignment, a socket of external synchonization and USB the interface (TVC can be power-supplied from the computer);
  • notebook;
  • cable of external syncronization;
  • electrical or fiber-optic communicational link with a PC;
  • software.

Basic software possibilities: 
  • to reproduce at a display a recorded image as a whole or its part in a selected by an operator scale;
  • to save a recorded image or a frames sequence at a hard or removed disk of a PC
  • to accumulate images at the CCD die (in a waiting mode) or programmatically at a PC;
  • to combine images (sum or difference of the last image input and a recorded file, sum or difference of two files);
  • to subtract regular noises and constant background
  • to rotate received image about the frame center selected for an angle selected by an operator e;
  • to form profiles of image relative brightness (intensity) according to one/two horizontal(X) and one vertical (Y) sections selected by an operator/ Meanwhile the section can be as in line form as well as in form of a control length window;
  • to measure width of related brightness profiles at 0.1 and 0.5 levels of their maximum and ranges of increase (decrease) of the profiles between 0.1 and 0.9 levels (0.9 and 0.1);
  • to measure related image brightness in a point or a band of horizontal and vertical sections crossing with a possibility of brightness scale spreading up to 2,5 or 10 times or its compressing up to 2,4,8 or 16 times ;
  • to vary velocity of special subimages movements under operation in a streak or multiframe image sweep mode;
  • to form lines of equal brightness (isophoto) at an image with selected by an operator level of brightness (from 0 to 255 and from 0 to 4095 to 8-bit and 12-bit modes respectively) or a set of the lines with selected brightness increment;
  • to realize digital correction of an image (brightness, contrast and range);
  • to reproduce an image in gray (black-and-white), blue and multicoloured (pseudo coloring of equibrightness ranges) palettes;
  • to inform user about ADC overfill. Meanwhile red color appear at the overbrightness sites of black-and-white and blue palette images, and white colour is lighted in case of multicoloured palette. This option can be turn on/off as user wish
