Optical component coherence reflectometer
WebOptical low-coherence tomography or reflectometry (OLCT or OLCR) as described in this section is a powerful technique to characterize the reflection spectrum and spatially resolve the coupling constants of a grating. However, there are other schemes that allow characterization, also based on time or frequency domain spectroscopy.

WebOct 20, 1993 · Abstract. We show that optical properties of dense biological tissues can be determined from backscattered power curves measured by a low-coherence reflectometer. Our measurement approach is based on a first-order scattering theory that relates the backscattered power to the total and backscattering cross sections of scatterers in a … 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.
