    • 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.
    • 一种用于客观地测量患者眼睛屈光力的眼屈光力测量装置,包括:投光光学系统,其包括光源并将测量光投射到患者眼睛的眼底; 光接收光学系统,其包括用作二维光接收元件的成像器装置,并接收从眼底反射的测量光; 以及操作部,其通过由成像器装置成像的测量光,基于二维图案图像来确定眼睛的眼睛屈光力。 光源是发射中心波长在约850nm至940nm范围内的光的超发光二极管或激光二极管。
