| 发明名称 | Optical device | ||
| 摘要 | A high-performance optical device is provided. An optical device includes a first transmitting portion that is disposed at the center of a predetermined area in a first substrate, a light-receiving portion that receives light passing through the first transmitting portion, N light-emitting portions (N is an integer of 2 or more) that are disposed around the first transmitting portion in the predetermined area, and a control circuit that controls the light-emitting portions. The control circuit is functionally divided into N control portions, namely, first to N-th control portions. The N control portions are disposed in areas overlapping the N light-emitting portions, respectively, when viewed from above. The optical device can reduce noise light and achieve a high S/N ratio, and also the sensitivity of the optical device can be improved. | ||
