    Abstract: A diffractive optical pattern generator includes a diffractive optical element layer, and a nanostructure layer configured for beam steering an input light applied to the diffractive optical pattern generator to at least one of a polar beam-steering angle that is measured in a plane that is substantially normal to a direction of the input light and an azimuth beam-steering angle measured with respect to the direction of the input light. A dynamic transmission layer may be included in which at least one region of the dynamic transmission layer may be selectively controllable to transmit light through or to block light from passing through the dynamic transmission layer. The nanostructure layer may include nanostructures having a periodicity ranging from 0.75 λ to 3 λ of a target wavelength λ. The nanostructure layer may be configured to beam steer light input to the DOE layer or beam steer light output from the DOE layer.

    Abstract: A biosensor includes a periodic crystalline structure first layer, and an amorphous crystalline structure second layer. The first and second layers are formed from a biocompatible silicone having a Young's Modulus E between 0.4 and 2.0 MPa. The biosensor has a pressure dependent NIR resonance peak shift of less than 15 nm over a field of view of 40°, and has an optical pressure sensitivity of between 0.38 and 2.6 nm/mm Hg. The biosensor may be formed by forming a 3D crystalline structure having a periodic amorphous crystalline first layer and an amorphous crystalline second layer. Voids of the 3D crystalline structure are filled with the biocompatible silicone/polydimethylsiloxane a material. The 3D crystalline structure is removed to form an inverse structure having a first volume of an amorphous arrangement of voids and a second volume of a periodic arrangement of voids.

    Abstract: A diffractive optical element (DOE) includes a substrate layer; and a nanostructure layer comprising nanostructures having a predetermined periodicity ranging from 0.75λ to 3λ of a target wavelength λ. The nanostructures are pillar-shaped nanostructures formed on a surface of the substrate layer, holes formed in the substrate layer, or a combination thereof. At least one nanostructure has a plan-view cross-sectional shape of a circle, an oval, a square, or a rectangle. The plan-view cross-sectional shape of at least one nanostructure includes a rounded corner having a corner radius selected based on a desired light dot nonuniformity of a diffraction pattern generated by the DOE. When the nanostructures are pillar-shaped, a refractive index of the nanostructures is greater than a refractive index of the substrate layer. When the nanostructures are holes, a refractive index of the nanostructures is less than a refractive index of the substrate layer.

    Abstract: A metalens includes one or more regions of nanostructures. A first region of nanostructures directs a first field of view (FOV) of light incident on the first region of nanostructures to a first region of an image plane. A second region of nanostructures directs a second FOV of light incident on the second region of nanostructures to a second region of the image plane in which the second FOV is different from the first FOV, and the second region of the image plane is different from the first region of the image plane. A third region of nanostructures directs a third FOV of light to a third region of the image plane, in which the third FOV is different from the first FOV and the second FOV, and the third region of the image plane is different from the first region and the second region of the image plane.

    Abstract: A camera system includes two or more sensor arrays and an optical path. The sensor arrays are on the same sensor chip. Each sensor array includes the same field of view (FOV) as each other sensor array. The optical path includes a main lens and a metalens that are shared by each sensor array, and a microlens associated with each sensor array. The metalens splits incident light into different spectrums of light and directs each respective spectrum to a corresponding sensor array. The different spectrums of light include at least two of visible light, near infrared light, shortwave infrared and longwave infrared, and at least one sensor array includes single-photon avalanche diodes. The image processor that provides image processing, object recognition and object tracking and/or image fusion functionality may be on the same sensor chip as the sensor arrays.

    Abstract: A pixel for an image sensor includes a microbolometer sensor portion, a visible image sensor portion and an output path. The microbolometer sensor portion outputs a signal corresponding to an infrared (IR) image sensed by the microbolometer sensor portion. The visible image sensor portion outputs a signal corresponding to a visible image sensed by the visible image sensor portion. The output path is shared by the microbolometer and the visible image sensor portions, and is controlled to selectively output the signal corresponding to the IR image or the signal corresponding to the visible image. The output path may be further shared with a visible image sensor portion of an additional pixel, in which case the output path may be controlled to selectively to also output the signal corresponding to a visible image of the additional pixel.
