WebWe describe a new optical low-coherence reflectometer for depth and lateral scanning without moving parts. The reflectometer covers a range of 0.4 and 1 mm in the depth and lateral dimensions, respectively. This level was accomplished by an acousto-optic deflector for lateral scanning and temporal-coherence gating for depth resolution.
