Two-wavelength opto-electronic vernier

The increasing of the measurement accuracy of pulses temporary situation in information sequences is an urgent problem. In these systems the information signal represents a number of optical pulses reflected from environment heterogeneous, coming during 1-10 mus depending on probing range. For registration and processing such signals was offered and realised opto-electronic vernier method of definition of a temporary situation of pulse information sequences. The method allows to make simultaneous measurement of the temporary situation of all entrance information signals with the permission in tens picoseconds. As against electronic vernier methods, in which two generators (clock and measuring) are used, in the offered device one opto-electronic recirculation generator with two optical wavelengths is used
