EYE REFRACTIVE POWER MEASURING SYSTEM

机译:眼折光功率测量系统

摘要

An eye refractive power measurement apparatus for objectively measuring eye refractive power of a patient's eye, includes: a light-projecting optical system that includes a light source and projects measurement light onto a fundus of the patient's eye; a light-receiving optical system that includes an imager device serving as a two-dimensional light-receiving element and receives the measurement light reflected from the fundus; and an operating section that determines the eye refractive power of the eye based on a two-dimensional pattern image by the measurement light imaged by the imager device. The light source is a super-luminescent diode or a laser diode that emits light having a center wavelength in a range of approximately 850 nm to 940 nm.
