Abstract
A fully static OCT device is proposed. The glass integrated optic technology is used to have a large Fourier interferogram along an edge of the glass chip bonded on CCD linear detector array without protective glass window. After having described the system principles, first measurements will be presented. For that an optical signal coming from a SLED is divided in two equal parts injected respectively in a reference input and a probe input. It will be demonstrated that an optical phase difference measurement close to 600µm in the air can be achieved with an optical contrast of 30dB.
