摘要: An optical image measurement device comprises: a light source configured to emit a low-coherence light; an interference-light generator configured to generate an interference light, by splitting the low-coherence light into a signal light and a reference light, and superimposing the signal light passed through a measurement object and the reference light passed through a reference object; a changer configured to change a difference in optical path length; a detector configured to detect the interference light; an image forming part configured to form an image of the measurement object within a predetermined frame based on the result of the detection; an analyzer configured to analyze the image, and specify a position of the image within the frame; and a controller configured to control the changer based on the specified position to change the difference so that an image newly formed is placed in a predetermined position within the frame.

摘要: A refractometer comprising an optical pattern-beam projection system for projecting a pattern,light beam onto the fundus of a tested eye to measure refractive power of the tested eye, and an optical light-receiving system for receiving the pattern light beam reflected at the fundus to compute the refractive power of the tested eye. A deflecting member is inserted into an optical path of the optical pattern-beam projection system for deflecting the pattern light beam with respect to an optical axis of the optical pattern-beam projection system and then projecting the deflected pattern light beam onto the fundus.
