Properties of an electron-optical single-frame camera enabling gating duration of 100 ns are reported. Gating is performed using the type LD-F-5 image intensifier tube. To intensify images on its screen, modular Gen I tubes LD-A-1.0 and LD-A-0.33 providing magnification of 1.0 and 0.33, respectively, were utilized. If necessary, the LD-A-0.33 tube may be substituted by any other image intensifier of the LDA series, the choice to be determined by type and size of an image-sensing CCD matrix with fiber-optical windows. The reported camera employs a 11 X 7.5 mm CCD matrix with 576 X 360 pixels. The LD-F-5 electron-optical shutter is controlled using radio-polar rectangular 100 ns pulses with an amplitude of 360 V, front and rear edge widths of 15 ns, and top slope within 3%. The system provides dynamic spatial resolution of around 20 l.p./mm, which is slightly worse than static resolution. The dynamic range of the registered optical signal is of the order of 300. The LD- F-5 output was intensified by the LD-A-1.0 and LD-A-0.33 tubes, whereupon it was sensed by the CCD matrix and recorded into a buffer memory. Data processing and documenting were performed using IBM PC/XT/AT with an interface system of data transfer from the buffer memory.
