Time-gated photorefractive holography for real-time depth-resolved imaging through turbid media

Not Accessible

Abstract

Optical imaging through biological tissue may provide a safe, real-time diagnostic tool for medical applications. Unfortunately the strong scattering of most tissue types (a typical scattering mean free path (MFP) is ~ 100 µm) preclude conventional imaging through even 1 mm. Confocal imaging can discriminate against scattered light to improve images [e.g. 1] but the integration times required to scan each pixel imply a long image acquisition time. For many applications it is preferable to acquire a whole image field simultaneously.
