摘要：
In a corneal measurement system, an optical element focuses an excitation light to an area of corneal tissue at a selected depth. In response, a fluorescing agent applied to the cornea generates a fluorescence emission. An aperture of a pinhole structure selectively transmits the fluorescence emission from the area of corneal tissue at the selected depth. A detector captures the selected fluorescence emission transmitted by the aperture and communicates information relating to a measurement of the selected fluorescence emission captured by the detector. A controller receives the information from the detector and determines a measurement of the fluorescing agent in the area of corneal tissue at the selected depth. The system may include a scan mechanism that causes the optical element to scan the cornea at a plurality of depths, and the controller may determine a measurement of the fluorescing agent in the cornea as a function of depth.
