Laser Doppler holography of the anterior segment for blood flow imaging, eye tracking, and transparency assessment

Laser Doppler holography (LDH) is a full-field blood flow imaging technique able to reveal human retinal and choroidal with high temporal resolution. We here report on using LDH in the anterior segment of eye without making changes instrument. Blood bulbar conjunctiva episclera as well corneal neovascularization can be effectively imaged. additionally demonstrate simultaneous holographic posterior segments by simply adapting numerical propagation distance plane interest. used this feature track movements retina pupil Finally, we show that light backscattered for retro-illumination segment. Hence digital opacities caused absorption or diffusion cornea lens.
