A device for measuring a single short pulse includes at least one measuring unit (D1, Dn) comprising a conductive line (L) connected to a set of photoconductors (A, B1-Bp), the line and photoconductors being placed between two nonconductors forming a single support in which the length of the line (x1) separating the photoconductors two-by-two is equal to the product of the propagation speed on the line with respect to the duration of the pulse concerning the number of measurement points, the lifetime of the majority carriers of the photoconductors being selected as being equal to or less than 10% of the duration of the pulse. The device makes it possible to obtain a temporal analysis or the autocorrelation of the pulse which may be an electromagnetic radiation or ionizing pulse or an electric pulse.
