Doppler holography system

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
