摘要: An optical type range finder apparatus for a motor vehicle. Dew condensation and deposition on an inner surface of an irradiation laser beam projecting window is prevented even in the environment where a front surface of the range finder is cooled down steeply, for ensuring a stable distance measuring performance. The apparatus projects outwardly an irradiation light beam (LE) from the motor vehicle and detects a distance between the motor vehicle and an object on the basis of known relation between the irradiation light beam (LE) and an echo light beam (LR) from the object existing in environment of the motor vehicle. An irradiation window (3a) includes a first light-transmissive panel (7) having a surface exposed to the exterior, a second light-transmissive panel (21) having a surface exposed to the interior of the range finder apparatus, and a heat insulation space (24) formed by an air layer confined between the first light-transmissive panel (7) and the second light-transmissive panel (21).

摘要: An apparatus for measuring blood flow repeatedly segmentally scans a region of in vivo tissue with a coherent light beam. Each scanning segment comprises a scanning period during which the light beam is scanned and a rest period during which the light beam is not scanned. During the rest period, the light beam is directed at a measuring point of the in vivo tissue. Measurement data is obtained dependent on the intensity of scattered light from the measurement point. The measurement data is time series data of chronological changes in the intensity of scattered light caused by blood in the in vivo tissue. The blood flow rate is calculated from frequency-analysis of the time series data.
