    Abstract: A diffractive light projection device includes a light source and a diffractive optical module. The light source emits a light beam. After the light beam passes through the diffractive optical module, a diffractive light is outputted from the diffractive optical module. The diffractive optical module includes plural diffractive optical elements, which are arranged in a stack form and made of different materials. Consequently, a usable wavelength range of the light beam is expanded. Since the usable wavelength range of the light beam to be incident on the diffractive optical module is expanded, the degree of freedom for designing the diffractive optical module is increased.

    Abstract: An optical lens includes a substrate, at least one derivative structure and a diffractive optical structure. 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 lighting apparatus includes a laser source module, a diffractive optical module and a reflective module. The laser source module emits a laser beam and is operated in a transverse mode or a multi-transverse mode or a condition of multiple lasing modes to generate the laser beam of a light-beam mode pattern. The reflective module receives and reflects the laser beam of the light-beam mode pattern, and the diffractive optical module diffracts the reflecting laser beam to form a structure light. The diffractive optical module includes a diffractive structure having a distribution pattern of microstructure consistent with the light-beam mode pattern.

    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.

    Abstract: A spatial information capturing device includes a structured light generation module, a camera module and a process controller. 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.

    Abstract: An injection mold and an optical lens produced from the injection mold are provided. The injection mold includes a disk-type mold base and a nozzle. A mold cavity chamber is defined by the disk-type mold base. The mold cavity chamber includes an optically effective central runner and an optically ineffective annular runner. Moreover, plural spoiler structures are formed in the optically ineffective annular runner. While a melt is injected from the nozzle to the mold cavity chamber, the plural spoiler structures provide the functions of disturbing the melt flow and decreasing the velocity of the melt in the optically ineffective annular runner. Consequently, before the optically ineffective annular runner is completely filled with the melt, the optically effective central runner is completely filled with the melt. Since no defect is formed in an optically effective zone, the yield of the optical lens is enhanced.

    Abstract: A lighting apparatus includes a laser source module and a diffractive optical module. The laser source module emits a laser beam. When the laser beam is operated in a transverse mode or a multi-transverse mode, the laser beam has a first laser beam pattern. The diffractive optical module is arranged in front of the laser source module or at a location that receives the laser beam, so that the laser beam is irradiated on the diffractive optical module. The diffractive optical module includes a first structure pattern corresponding to the first laser beam pattern. After the laser beam is diffracted by the first structure pattern, a first structured light with a first structured light pattern is generated.
