An optical touch system includes a substrate, a glass module, two light sources, three reflective clothes, two image sensors and a processing module. The glass module is disposed at one side of the substrate. The two light sources are respectively disposed at two terminals of the glass module. The three reflective clothes are disposed on the edges of the substrate contiguously. A touch region is formed among the three reflective clothes and the glass module for reflecting the light emitted from the two light sources. The two image sensors are disposed respectively next to the two light sources and used for capturing images in the touch region. The processing module is used for determining whether a touch action is performed according to the images in the touch region.

Optical touch system and method

The invention provides an electronic equipment having a laser component and capability of inspecting leak of laser and an inspecting method for inspecting leak of laser thereof. The electronic equipment according to the invention includes a three-dimensional image-capturing device. According to the invention, the three-dimensional image-capturing device is controlled to capture a two-dimensional image, and to measure an actual depth map. The captured two-dimensional image is processed to obtain an estimated depth map. The invention selectively determines that the laser component occurs leak of laser or malfunctions in accordance with the estimated depth map and the actual depth map.

Electronic equipment having laser component and capability of inspecting leak of laser and inspecting method for inspecting leak of laser thereof

The invention provides a system and method for inspecting a three-dimensional sensor. According to the invention, a light source is controlled to emit a light of a known phase, and the known phase of the emitted light is altered by at least two known phase values. The three-dimensional sensor is driven in sensing the light reflected by the inspecting space to capture an image. In accordance with the captured image and the relative angle and the active brightness of each pixel thereof and the plurality of reference data, at least two quality data relative to the three-dimensional sensor are calculated.
