    摘要: An ocular blood-flow meter includes an optical system for applying measuring light to a blood vessel of a subject eye, and for receiving light scattered by the blood vessel of the subject eye. A mechanism is provided for changing a direction in which the measuring light is applied and a direction in which the scattered light is received so as to enable a plurality of measurements in different directions. A controller performs the plurality of measurements in the different directions by using the optical system and the mechanism so as to obtain information concerning a blood flow. An output device provides a received-light signal obtained by the optical system or the information concerning the blood flow. An input device enables an operator to select a re-measurement operation in a desired direction from the different directions and to instruct the selected re-measurement operation.

    摘要: A Doppler velocimeter includes an illumination system for illuminating a blood vessel with a light beam, a detector for detecting Doppler-shifted scattered light produced from blood flowing in the blood vessel, and a processor for obtaining a blood flow velocity by analyzing a signal from said detector. The processor compares an actual power spectrum obtained by frequency-analyzing the signal with a theoretical power spectrum obtained using a frequency as a parameter while changing the parameter.
