SYSTEMS AND METHODS FOR CORNEAL PROPERTY ANALYSIS USING TERAHERTZ RADIATION

摘要

Methods and systems for analysing a property of a cornea of an eye using terahertz (THz) radiation are provided. The method includes projecting a first THz wave onto a surface of the cornea and detecting a first reflected wave being a reflection of the first THz wave reflected from the surface of the cornea. The method further includes deforming the cornea by projecting visible light or puffing air to the surface of the cornea, projecting a second THz wave onto the surface of the cornea after the deforming, and detecting a second reflected wave being a reflection of the second THz wave reflected from the surface of the cornea after the deforming. Finally, the method includes calculating the property of the cornea based on the first reflected wave and the second reflected wave. The invention particularly relates to systems and methods for corneal elasticity and/or rigidity analysis using terahertz (THz) time-domain spectroscopy.
