Holographic laser Doppler ophthalmoscopy

Opt Lett. 2010 Jun 15;35(12):1941-3. doi: 10.1364/OL.35.001941.

Abstract

We report laser Doppler ophthalmoscopic fundus imaging in the rat eye with near-IR heterodyne holography. Sequential sampling of the beat of the reflected radiation against a frequency-shifted optical local oscillator is made onto an array detector. Wide-field maps of fluctuation spectra in the 10 Hz to 25 kHz band exhibit angiographic contrasts in the retinal vascular tree without requirement of an exogenous marker.
