摘要： A process and apparatus for measuring an axial eye length takes the steps of projecting monochromatic coherent light of which wavelengths are variable onto an eye to be tested, causing an interference between reflected light from a retina of the eye and reference light corresponding to the retina to generate interference signals while reflected light from a cornea of the eye is interfered with reference light corresponding to the cornea to generate interference signals, mixing these interference signals to generate beat signals while varying the wavelength, and measuring an axial eye length based on the beat signals.

摘要： A light image of a scale, which bears length or angle information recorded in the form of a bright and dark bit pattern, is projected onto the light receiving surface of a storage effect type sensor, whereby a charge pattern data corresponding to the projected image is formed. Before the regular read-out of the charge pattern data thus formed from the sensor, the sensor is scanned at least once at a higher scanning frequency than the frequency for the regular data read-out. From the data thus read out, read-out data that obtained in the absence of illumination light is subtracted, and the resultant data which is free from error component is processed to obtain a final measurement of the length or angle.
