Methods and systems for dry eye analysis using terahertz (THz) radiation. The method includes projecting a THz wave onto a surface of an eye and detecting a reflected wave being a reflection of the THz wave reflected from the surface of the eye. The method further includes analysing properties of the eye in response to the THz wave reflected from the surface of the eye, the properties of the eye including thickness of the eye's cornea and ambient tissues, and analyzing the properties of the eye comprises measuring the thickness of the cornea and/or the ambient tissues and/or measuring an amount of chemical components of one or more of the eye's layers.

Systems and methods for dry eye analysis using terahertz radiation

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, 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.
