Direct operation over the UWB optical signal transferred with pseudo-random carrier

Abstract

Modulation of white light emitted by the thermal source using simple optical systems capable to realize UWB information transfer are considered and realized. The experiments fulfilled permitted to estimate the minimum time resolution of the detection of signal with two-beams interferometer as 3.6 fs. For the effective time encoding method, the system based on Michelson echelon is proposed, its theory is developed using δ-wave approach for any angle of the beam incidence and scattering. Peculiarities of the echelon pulse response are analyzed. In addition, the simple method of digital encoding of the light flow with the pack of thin glasses of different thickness is demonstrated.
