Abstract: An optical apparatus includes plural optical lens groups, an optical sensor and a casing. After a light beam passes through any of the plural optical lens groups, a travelling direction of the light beam is changed. Moreover, after the light beam passes through at least one of the plural optical lens groups, the light beam is sensed by the optical sensor and converted into an image signal by the optical sensor. The plural optical lens groups and the optical sensor are accommodated and fixed within the casing. The optical apparatus has a single optical lens module, and is able to implement different optical function simultaneously. Consequently, the overall volume of the optical apparatus is minimized, and the fabricating cost of the optical apparatus is reduced.

Abstract: An optical device includes a structured light generation unit and a beam splitter assembly. The structured light generation unit generates a structured light. The beam splitter assembly is arranged in a travelling path of the structured light. The beam splitter assembly includes a semi-transmissive semi-reflective structure. A portion of the structured light is transmitted through the semi-transmissive semi-reflective structure of the beam splitter assembly and projected on a projection surface. Consequently, a first structured light pattern is formed on the projection surface. Another portion of the structured light is reflected by the semi-transmissive semi-reflective structure of the beam splitter assembly and projected on the projection surface along a different path. Consequently, a second structured light pattern different from the first structured light pattern is formed on the projection surface. The number of structured light patterns or the projected area is correspondingly adjusted.

Consequently, the overall volume of the optical apparatus is minimized, the fabricating cost of the optical apparatus is reduced, the assembling process is simplified, and the number of components to be assembled is reduced.

Abstract: A structured light generation module includes a light source, a collimating optical element and a beam-diffusion optical element. The light source provides a source beam with a source beam size. After the source beam is collimated by the collimating optical element, a collimated light beam is generated. After the collimated light beam is diffused by the beam-diffusion optical element, a structured light with a beam diffusion angle relative to the collimated light beam is generated. The beam-diffusion optical element includes plural lenses, and the plural lenses are repeatedly distributed in one dimension. The pitches and the orientations of the lenses are specially designed. Consequently, the structured light generation module is capable of generating diversified structured light patterns.

Abstract: A lighting apparatus includes a structured light generation unit and a controlling unit. The structured light generation unit includes plural light sources and an optical element group. After plural light beams from the plural light sources pass through the optical element group, a first structured light pattern corresponding to a first light source is projected on a first position of the projection surface and a second structured light pattern corresponding to a second light source is projected on a second position of the projection surface. The first position and the second position are different. The controlling unit controls the first light source and the second light source to emit the light beams according to a time sequence. Consequently, the first structured light pattern and the second structured light pattern are projected on the projection surface according to the time sequence.

Abstract: A detecting method and an optical apparatus using the detecting method are provided. The optical apparatus includes a structured light generation unit and a sense judging unit. When a structured light from the structured light generation unit is projected on a test surface, a test pattern and a test light spot are shown on the test surface. The sense judging unit judges whether the test surface is flat according to a deformation amount of the sensed test pattern, and acquires a distance between the test surface and the optical apparatus according to an area of the sensed test light spot. The detecting method judges whether a test surface is flat and detect a distance of the test surface. Since the structured light is used to detect the distance and the flatness of the test surface, the measuring complexity is reduced.

The first optical lens module includes a first optical lens and a first optical sensor. According to the working distance or the equivalent focal length of the first optical lens module, the size of the first optical lens and the size of the first optical sensor, the maximum field of view is acquired. Consequently, the size of the first opening is determined, and the casing is slim. Under this circumstance, the image-capturing and light-sensing optical apparatus complies with the purpose of miniaturization.

Abstract: An assembly of zoom lens module includes a main lens, plural associate lens and a rotator mechanism. The plural associated lens disposed around the mail lens and each associated lens has a shiftable lens element shifted by the rotator mechanism. When the rotator mechanism rotates, plural shiftable lens elements are shifted such that the zoom effects of the plural associate lens can be changed. Therefore, the assembly of zoom lens module may provide plentiful zoom effects without increasing the volume, particularly the total track length, and weight of the zoom lens assembly.

Abstract: A structured light generation device is equipped with a lens unit. The lens unit is installed in a compact housing of the structured light generation device such that it can be workable for two different optical path lengths, and hence for a range of parameter, such as effective focal length, back focal length, or working distance. By the lens unit, an infrared laser spot is collimated into a linear infrared laser beam or specific light pattern if with a free-form type structure formed on a surface where the free form contains diffractive, refractive, and/or reflective optical structures simultaneously or effectively. Consequently, the infrared laser spot is shaped into a structured light for detection or interactive action.
