Abstract: An optical assembly to enable distortion compensation and enhanced image clarity is provided. The optical assembly may include an optical stack, such as pancake optics. The optical assembly may also include at least two optical elements. The optical assembly may further include at least one spatially located, free form optical component between the at least two optical elements, wherein the spatially located, free form optical component provides distortion compensation and enhanced image clarity. In some examples, the spatially located, free form optical component may have a plurality of regions having different diffraction designs. In some examples, , the spatially located, free form optical component may also utilize a curvature (i.e., may have a curved surface) to implement a phase change profile that may provide distortion compensation.

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.
