Abstract: A non-contact laser triangulation scanning apparatus for generating a three-dimensional image of the surface of an object based on the 3D surface position and surface contrast information. The apparatus comprises a laser source, a first optical unit, a second optical unit, a photosensitive positional detector having a plurality of sensor elements, and an incident light measurement device. According to generated timing signals having a predetermined time interval, a reset timing of the sensor elements of the photosensitive positional detector is controlled. The incident light measurement device measures an amount of a certifying laser light after one timing signal. An amount of a measurement laser light is determined dependent on the measured amount of the certifying laser light. The three-dimensional image is generated by combining position data derived from signals of the positional detector with contrast data derived at least from signals of the incident light measurement device.

Abstract: An artificial nail or decorative cover is used to cover a clip set. The clip set combines the nail cover or decorative cover with a plastic clip. The nail cover is a cover body with an outer surface curved like a human nail and has a wall running sideways at an inner surface of the cover. A fitting ditch between the inner surface of the cover and the thin plate wall is provided on the thin plate wall. This artificial nail cover or decorative cover can be also attached with the plastic clip to cover the clip set.
