    • An optical touch apparatus includes a light source emitting module, an optical module, a light sensing module, and a processing module. The optical module and the light sensing module are set on a first side and a second side of a surface of the optical touch apparatus. The light source emitting module sequentially emits a first light source and a second light source. A plurality of scanning lights of the second light source is uniformly distributed above the surface. The optical module receives the first light source and uniformly emits a plurality of lights. The light sensing module generates a first sensing result and a second sensing result based on the conditions of receiving the lights and scanning lights respectively. The processing module determines at least one touch point location corresponding to at least one object on the surface based on the first sensing result and the second sensing result.

    • An optical coherence tomography apparatus includes a light source, a light coupling module, and an optical path difference generating module. The light source emits a coherent light. The light coupling module divides the coherent light into a first incident light and a second incident light. The first incident light is emitted to an item to be inspected and a first reflected light is generated. The second incident light is emitted to the optical path difference generating module, a second reflected light is generated according to the second incident light by the optical path difference generating module through changing the transparent/reflection properties of at least one optical devices of the optical path difference generating module, so that there is a optical path difference between the first reflected light and the second reflected light.
