Abstract

PURPOSE:To heighten sensitivity, by arranging a plurality of photosensitive units at a spacing on a straight line or a curve and providing an optical means for condensing light proceeding in a direction perpendicular to the arrangement direction of the photosensitive units, onto them. CONSTITUTION:A cylindrical lens 2 is provided as an optical means for condensing light proceeding in a direction perpendicular to the direction X of arrangement of a plurality of photosensitive units 1, onto them. Unless the cylindrical lens 2 is present, only light in a hatched region is detected by the photosensitive units 1 when parallel rays of light proceed rightward in Fig. Since the cylindrical lens 2 is present in fact, light in a larger region is received by the photosensitive units 1. Therefore, the sensitivity to the light is heightened. Because the cylindrical lens 2 is provided, the sensitivity of a detector and the accuracy of measurement are raised.
