Profile sensor


Outputs the incident position coordinate data of light spot,
built-in center-of-gravity calculation circuit


The S15366-512 is a profile sensor with a center-of-gravity calculation circuit for detecting the incident position of the light spot. In the photosensitive area arranged two-dimensionally, the photosensitive area for the X-direction projection data is connected in one vertical row, and the photosensitive area for the Y-direction projection data is connected in one horizontal row using metal wiring. The sum of outputs of the photosensitive area is obtained for each line in the X and Y directions. Projection data can be obtained by obtaining the data of all lines in order. Since the data size of the projection data is small, position detection and moving object detection can be performed faster than normal area image sensors. The center-of-gravity calculation circuit is built-in, so the center-of-gravity calculation result of light spot is output. It also has a built-in light spot automatic tracking mode.
