Abstract: According to examples, an optical assembly for a head-mounted display (HMD) device may include a compensation element to modify a phase of a first light arriving from an environment outside the head-mounted display (HMD) device; a transparent display to present an image or a video and to pass through the phase-modified first light; and a focus element to focus the phase-modified first light and a second light from the transparent display on an eyebox. The optical assembly may reduce one or more aberrations in the first light or the second light. The focus element may be a metalens, a light field lens, a solid optical lens, or an optical configuration with two optical elements including an air gap between the two optical elements. The compensation element may be a free-form phase plate.

Abstract: A system and method for high-throughput testing and module integration of rotationally variant optical lens systems is provided. In some examples, the system may be a metrology system that includes a light source to generate optical illumination. The metrology system may also include a null element. The null element may generate, using the optical illumination from the light source, a prescribed wavefront corresponding to a unit under test (UUT). In addition, the metrology system may further include a null element fixture to position the null element with respect to the unit under test (UUT).

Abstract: According to examples, a system for designing optical components to provide passive athermalization and aberration correction is described. The system may include a processor and a memory storing instructions. The processor, when executing the instructions, may cause the system to select one or more optical elements to be included in the optical component based on the received design specifications, select one or more optical element configurations based on the selected one or more optical elements and implement an optimization function to optimize the selected one or more optical element configurations. The processor, when executing the instructions, may then determine if the one or more optical element configurations meet one or more initial specifications, enable one or more adjustment(s) to the one or more optical element configurations and determine if an optical element configuration meet one or more additional specifications.

Abstract: According to examples, a remote sensing security system that includes a dual-purpose camera system comprising at least one dual-purpose camera is disclosed. The dual-purpose camera may include a visible light sensor that detects one or more of objects and movements in the visible spectrum and an infrared (IR) sensor that detects one or more of objects and movements in the IR spectrum. The data from the dual-purpose camera system may be transmitted to a cloud server which may process the data to identify the detected objects and/or movements. If any objects and/or movements related to an emergency to are identified, then the type of emergency may also be determined and alerts may be transmitted to one or more client devices which may include head-mounted display (HMD) devices.
