| 摘要 |
An optical sensor is proposed. The optical sensor comprises a first substrate, a second substrate, a membrane, and an optical gate. The first substrate has a concave structure having a first optical micro-reflection surface and a second optical micro-reflection surface formed thereon. The second substrate has a second concave structure having a third optical micro-reflection surface and a fourth optical micro-reflection surface formed thereon. The optical gate is disposed on the membrane within the first concave structure. The membrane is disposed between the first substrate and the second substrate. |
