Abstract
Automatic processing for pulses with duration lying in microsecond and nanosecond ranges takes a rising interest. However, the available digital electronics facilities are not able due of their low speed to convert and store these signals directly with required resolution for a detail analysis of pulse response shape and other parameters. Therefore, researchers are forced to use another facilities, for instance, a storage oscilloscope. An oscilloscope as the most widely used apparatus in researching of unsteady processes gives good results, when a manual mode of operation is used. However, it is not adapted to obtaining both the express information and the information that requires a quantitative analysis. Also, it is impossible to provide the acquired data with fast processing, that is necessary for industrial products testing. Often oscilloscope images have low brightness and low contrast. To overcome these problems we have to create hardware and software for the microsecond-range oscilloscope image processing. The structure of hardware for image collection (Picture Transformer - PT) is given in Fig.1. PT consists of four units: an image converter (IC); a TV camera; a TV-camera controller, which makes the time discretization and digitization of a videosignal and the image framing according to the video synchronizing signals; an image memory for image storing in frame size. The main operational characteristics are: image frame size - 512x512 pixels; resolution in brightness-64 gray levels; time of the frame storing into the image memory - 40 ms; speed of the interchange with computer - maximum 2.5 Mb/s; power consumption - 80 VA; physical dimensions 470x310x60 mm3 added by TV camera and IC.
