In this paper we propose a novel technique to generate variable true time micro-delay for fibre-based optical coherent tomography (OCT) using two Opto-VLSI processors. The technique offers broadband high resolution scanning depth without moving parts. The beam steering and multicasting capabilities of the Opto-VLSI processors provide a valuable scanning tool allowing the delay generator to jump between nonadjacent depths and realising multiple delays simultaneously. Experimental results achieved maximum 500 nm delay with 3dB bandwidth is more than 55nm a centre wavelength 1550nm.
