Abstract

Doppler holography is a system using ultrahigh-speed digital holography for quantitative blood flow analysis from retinal and ocular imaging.

Clinical Specifications

Primary Applications:

  • Diagnosis and monitoring of ocular vascular diseases

  • Cardiovascular risk stratification through retinal microvasculature analysis that reflects systemic vascular health

  • Assessment of conditions including hypertension, atherosclerosis, diabetes, and impaired perfusion regulation

Clinical Features:

  • Optimized for standardized retinal hemodynamics measurements

  • Ensures patient comfort, reliability, and accuracy with minimal instrument tuning

  • Quantitative blood flow analysis from Doppler holography data

Technical Specifications

Core Technology:

  • Built around an inline Mach-Zehnder interferometer operating in the near-infrared range

  • Combines light backscattered from the patient's ocular fundus with a coherent reference beam

  • Uses ultrahigh-speed digital holography for precise imaging

System Capabilities:

  • Real-time interference pattern capture by high-speed streaming camera

  • Reliable, precise, quantitative Doppler imaging for clinical applications

Software Features:

  • Intuitive user experience with seamless, one-click acquisition process

  • Fully automated and streamlined data analysis eliminating need for user intervention
