<p>The device comprises a high speed oscilloscope (1) on the screen of which is formed by scanning a light path representative of the amplitude variation as the function of the time of the signal to be processed. Each point of such path is transformed by an astigmatic optical system (2) into a light segment of constant length projected with off-set on a strip of photodiodes (3) so that each sensor element of the strip receives a light band of a height proportional to the ordinate of the corresponding point of the path. An electronic circuit (4) reads the strip after a predetermined number of passages of the signal. The result is displayed on an oscilloscope (5) and stored in a memory (6) after analog-digital conversion.</p> |
