Abstract: 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.

Abstract: 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.

Abstract: A closure mechanism for an opening defined by a center and an outer edge, includes multiple segments which can all together close the opening. Each segment has a first pivot lever and a second pivot lever and is controlled by the pivoting movements thereof. The segment along with its pivot levers forms a four-bar linkage. All first pivot levers are attached to a first base and all second pivot levers are attached to a second base. The relative movement between the first base and the second base leads to a drive movement for the pivot levers, wherein the second pivot lever is mechanically coupled to the first base via a cam gearing mechanism.

Abstract: A zoom optical system comprises, in order from an object: a first lens group (G1) having positive refractive power; a second lens group (G2) having negative refractive power; and a subsequent group (GR) including at least one lens group. Upon zooming, distances between the first lens group (G1) and the second lens group (G2) and between the second lens group (G2) and the subsequent group (GR) change. The subsequent group (GR) comprises a focusing group (Gfc) having negative refractive power for focusing. The first lens group (G1) comprises a 1-1st lens that has positive refractive power and is disposed closest to the object. A following conditional expression is satisfied:
