Abstract: An optical apparatus includes a structured light generation unit, a conversion lens module, a collimating lens and a casing. The structured light generation unit outputs a structured light. The light beams from the structured light generation unit are expanded by the conversion lens module. The expanded light beams are collimated by the collimating lens. After the light beams pass through the conversion lens module and the collimating lens, the light beams are projected to a projection surface. Consequently, a structured light pattern is formed on the projection surface. All conversion lenses of the conversion lens module have negative optical power. Consequently, the area of the structured light pattern on the projection surface is wider. Moreover, the structured light generation unit and the conversion lens module can be accommodated within the casing having a smaller thickness.

Abstract: An optical apparatus includes a photosensitive element, a lens and a microstructure unit. The microstructure unit is arranged between the photosensitive element and the lens. After plural light beams passing through the lens are received by the microstructure unit, travelling directions of the plural light beams are changed. Consequently, at least a portion of the plural light beams is guided to the photosensitive element. In such way, the light collecting efficacy of the photosensitive element is enhanced.

The substrate has an optically operable region and a derivatively operable region. The derivatively operable region is arranged around the optically operable region. The derivative structure is disposed on the derivatively operable region to increase structural strength of the optical lens and to reduce the stray light as being assembled in a module. The diffractive optical structure is disposed on the optically operable region and includes a microstructure pattern for generating a desired light and/or correcting the optical defects. Consequently, the optical lens is suitable for miniaturization and assembling applications to a module.

Abstract: A structured light generation device includes a laser light source module and a diffractive optical element. After a non-collimated light beam from the laser light source module is received by a diffraction layer of the diffractive optical element, the non-collimated light beam is modulated as an optical information-bearing light. Since no collimator is between the laser light source module and the diffractive optical element, the spacing distance between the laser light source module and the diffractive optical element is shortened. Consequently, the overall structured light generation device is slim.

The structured light generation module provides a structured light pattern to a target object, so that an evaluation pattern is formed on the target object. The camera module includes a lens group, an optical encoder and a sensing unit. The optical encoder has a reference pattern. The reference pattern and the evaluation pattern have at least one corresponding pattern feature. In addition, both of the reference pattern and the evaluation pattern are projected on the sensing unit. The process controller compares a pattern feature difference between the reference pattern and the evaluation pattern, and realizes a spatial distance information of the target object according to a result of comparing the pattern feature difference. Hence, the configuration or structure of the spatial information capturing device is simplified.

The optical device includes a structured light generation unit and a conversion lens module. The conversion lens module is arranged between the structured light generation unit and a projection surface. The structured light generation unit outputs a structured light.
