摘要： An optical lens module includes a lens element and an adjustable aperture module disposed at object side of the lens element, and the adjustable aperture module includes a blade assembly and a driving component. The blade assembly includes rotatable blades disposed around an optical axis of the lens element to form a light passing aperture. Each rotatable blade includes a rotatable portion and a light blocking portion. The light blocking portion extends and tapers away from the rotatable portion. The rotatable portion has a positioning hole and a dynamic hole. The positioning hole enables rotation of the rotatable blade, and the dynamic hole is disposed close to the positioning hole. The driving component includes a rotatable element corresponding to the dynamic holes to rotate the rotatable blades, to thereby vary aperture size. The light blocking portion includes a protruding segment which extends and tapers toward the light passing aperture.

摘要： The present disclosure relates to limitation of noise on light detectors using an aperture. One example implementation includes a system. The system includes a lens that focuses light from a scene toward a focal plane. The system also includes an aperture defined within an opaque material. The system also includes a plurality of waveguides. A given waveguide of the plurality has an input end that receives a portion of light transmitted through the aperture, and guides the received portion toward an output end of the given waveguide. A cross-sectional area of the guided portion at the output end is greater than a cross-sectional area of the received portion at the input end. The system also includes an array of light detectors that detects the guided light transmitted through the output end.

摘要： A camera module includes a fixed base, a carrier, an elastic element, an imaging lens, a coil, a magnetic element, a connection wire and a light-blocking coating. The carrier is disposed opposite to the fixed base and has a bobbin. The elastic element is connected to the fixed base and the carrier so as to provide freedom of movement of the carrier with respect to the fixed base. The imaging lens is disposed on the carrier and has an optical axis. The coil is disposed on the carrier. The magnetic element is disposed corresponding to the coil so as to provide a driving force for moving the carrier. The connection wire is disposed on the bobbin and electrically connected to the elastic element and the coil, and the connection wire has at least part facing towards the optical axis where the light-blocking coating is disposed.

摘要： A viewing angle limiting apparatus and a display apparatus are provided. The apparatus comprises a first optical member having a plurality of lower light shielding members, and a second optical member having a plurality of upper light shielding members and facing the first optical member. Each of the plurality of upper light shielding members may be spaced apart from each of the plurality of lower light shielding members in a thickness direction of the first optical member and disposed to be alternate with each of the plurality of lower shielding members. Therefore, since a length of each of the lower light shielding members and the upper light shielding members may be formed to be short, the light shielding members may be manufactured more easily than the case that one light shielding member is provided longitudinally up and down, and a defect rate may be lowered, whereby productivity may be enhanced.
