Abstract: A head-mounted eye tracking system including an optical combiner, an eye tracker and a signal processor is provided. The optical combiner includes an optical coupler. The eye tracker is at least partially disposed on the optical combiner and is suitable for sensing an eyeball movement of a wearer. The eye tracker includes a plurality of light-emitting devices and a plurality of sensing devices. The plurality of light-emitting devices are suitable for emitting tracking beams. The plurality of sensing devices are suitable for receiving the tracking beams reflected by the eyeball of the wearer. The signal processor is signally connected to the eye tracker.

Abstract: An apparatus for measuring a curvature of a thin film includes a light emitting module, a first optical module, a second optical module, a third optical module, and an image analysis module. The light emitting module emits a single laser to be used as an incident light. The incident light is transmitted through a first optical path provided by the first optical module, then the incident light is guided by the second optical module to be incident to the thin film through a second optical path. A reflected light reflected by the thin film is transmitted through the second optical path, then guided by the third optical module to be transmitted along a third optical path. The image analysis module determines the curvature of the thin film according to the characteristic of the reflected light.
