Paper Abstract

In this communication a new manner to do away with classical optical delay line problems is proposed. According to Young's holes experiment and thanks to integrated optics, we have been able to realize a device producing spatially distributed fringes in the air. The acquisition time and the dynamic are governed by the CCD linear detector reading speed and size. The theoretical optical delay path is around 1.5 mm and the interferogram acquisition speed approaches 3 kHz. Moreover, this new approach offers all the advantages of the integrated optic technology: mechanical and thermal stability, no more alignment problem, low cost technology (ion-exchange) and small size chip. The study, the fabrication and the characterization of the first optical chip are described. First OCT measurements are also presented.
