PROBLEM TO BE SOLVED: To provide a device comprising plural light receiving elements disposed as an array in the same plane by performing operation of reading information of the light receiving elements in order at the same timing for setting space resolution and/or view field changeable. SOLUTION: An optical detector comprising plural light receiving elements 201 (11, 12, 13...) each integrated with a gate switch 202 is provided with a horizontal direction reading control device (H-device) 203 and a vertical direction reading control device (V-device) 204. The gate switch 202 on the first line is opened by the V-device 204, and simultaneously, the gate switches 202 are opened from the first line on in order by the H-device 203. Next, designation by the V-device 204 is changed to the gate switch 202 on the second line, and the gate switches 202 are similarly opened from the first line on by the H-device 203, so the light receiving elements 201 in each line are read in order. Since all the light receiving elements 201 are read similarly, activity of a living body is measured. |
