    Abstract: A signal detector and/or display system includes a bleachable dye medium whose transparency to optical signals is nonlinearly related to the intensities of coincident signals transmitted through the medium. A pulse of picosecond width is detected and the pulse width measured by causing the pulse to overlap itself within the medium. A complex signal is displayed by sampling the signal with a picosecond pulse within the medium.
