Paper Abstract

We demonstrate axial-lateral parallel time-domain optical coherence tomography using an optical zoom lens and highorder diffracted lights at 830 nm to adjust imaging range. Our 2-D CCD camera (640 x 480 pixels, 207fps) measured a depth-resolved interference image using diffracted light as the reference beam and a linear illumination beam without any scan. The lateral range can be varied continuously from 6.4 to 1.6 mm by increasing the magnification of optical zoom lens. The axial range can be adjusted discretely from 1st to 7th orders because we used a diffraction grating with 300 lines/mm in a 830 nm wavelength region.
