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 use of the structured light to judge the category of the under-test object can achieve the anti-counterfeiting efficacy.

Moreover, the lens unit constructed two different optical path lengths within the housing. By the lens unit, light beams from the light source are collimated and converted into linear light beams. The linear light beams are locally overlapped or globally overlapped. Consequently, the light beam from the light source is shaped into a linear structured light or a linearly-overlapped structured light for detection.

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: An optical apparatus includes plural optical lens groups with a specified field of view, 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.

In short, the optical apparatus has a single optical lens module, and is able to implement different optical functions simultaneously. Consequently, the overall volume of the optical apparatus is minimized, and the fabricating cost of the optical apparatus is reduced.
