An optical sensing system is provided, including a sensing module, a light emitter, and a light receiver. The sensing module has a substrate, an optical waveguide disposed on the substrate, and a sensing membrane disposed on the optical waveguide for carrying a specimen. The light emitter emits a sensing light to the optical waveguide, and the light receiver receives the sensing light that propagates through the optical waveguide.

A camera module, a camera assembly, and an electronic device are disclosed, which relate to the field of smart devices. The camera module includes a fixing member, a lens assembly, an image sensor, and a focusing assembly. The image sensor is configured to receive light transmitting through the lens assembly. In the focusing assembly, a first light-redirecting member is configured to redirect the light transmitting from the lens assembly to the image sensor; a second light-redirecting member is configured to redirect the light redirected by the first light-redirecting member, and configured to be movable relative to the fixing member to change a transmission distance of the light from the lens assembly to the image sensor.

A driving mechanism is provided, including a fixed part, a movable part for holding an optical element, and a driving assembly. The movable part is movable relative to the fixed part, and the driving assembly is configured to drive the movable part to move relative to the fixed part. Light reaches the optical element along an incident direction and leaves the optical element along an exit direction, wherein the exit direction is not parallel to the incident direction.

A display apparatus has a display to emit image-bearing light to a prism assembly that defines an optical path between an incident surface of the prism assembly and an output surface that is orthogonal to within +/−30 degrees relative to the incident surface, wherein the prism assembly has a curved reflective surface opposite the incident surface. The prism assembly encases a beam splitter at an oblique angle to the defined optical path and to both the incident and the output surface of the prism assembly. A shim, in contact against the display surface and against the incident surface of the prism assembly, defines a sealed air gap for light between the display surface and the incident surface. A frame houses the display, the shim, and the incident surface of the prism assembly, wherein the frame further provides connection features for coupling the apparatus to a head-worn article.

A camera module includes a housing; a lens module accommodated in the housing and configured to adjust focus or adjust focus magnification; and an optical path conversion module accommodated in the housing and configured to convert an optical path. The optical path conversion module includes a prism; a first movable body accommodating the prism; a fixed body accommodating the first movable body; a first driving unit enabling first rotational driving of the first movable body, relative to the fixed body; and a second driving unit enabling second rotational driving of the first movable body, relative to the fixed body.
