摘要： A method of fabricating a visible spectrum optical component includes: providing a substrate; forming a resist layer over a surface of the substrate; patterning the resist layer to form a patterned resist layer defining openings exposing portions of the surface of the substrate; performing deposition to form a dielectric film over the patterned resist layer and over the exposed portions of the surface of the substrate, wherein a top surface of the dielectric film is above a top surface of the patterned resist layer; removing a top portion of the dielectric film to expose the top surface of the patterned resist layer and top surfaces of dielectric units within the openings of the patterned resist layer; and removing the patterned resist layer to retain the dielectric units over the substrate.

摘要： A camera assembly includes an image sensor having a field of view corresponding to a scene, an infrared (IR) illuminator configured to selectively illuminate the scene, and a single-piece cover element positioned in front of the image sensor and the IR illuminator such that light from the IR illuminator is directed through the cover element along a first light path and light from the scene passes through the cover element along a second light path prior to entering the image sensor, the cover element including a first portion between the first light path and the second light path, the first portion being substantially opaque to IR and/or visible light.

摘要： The disclosure refers to the anti-blur infrared lens for the panoramic camera system, also known as Infrared Search and Track (IRST), using a 1280×1024 resolution sensor with a working F-number of 2. The lens operates in the mid-infrared wavelength range of 3-5 μm, using a fast steering mirror (FSM) and a pair of lenses with extended polynomial surfaces to prevent image blur during integration time. The optical image captured by the lens always maintains sharpness during the change of rotation angle of the device by changing the angular position of FSM. The lens is capable of observing with wide angle-of-view and large rotation angle compensation ability, ensuring long detection distance.
