Abstract: Embodiments described herein provide an asymmetric optical metrology system for evaluating and inspecting the performance of optical devices, such as augmented reality (AR) waveguide combiners. The system utilizes an asymmetric optical configuration and fly-eye illumination to enhance the detection limit of image sharpness and the accuracy of luminance uniformity. By employing different lenses with various focal lengths, the system increases the sampling rate in the angular space, addressing the challenges of form factor limitations and pixel density inherent in conventional metrology tools. Embodiments described herein offer improved contrast and sharp image details, as well as a compact design, making it suitable for the development, optimization, and quality control of optical devices, such as AR waveguide combiners.

Abstract: Embodiments described herein relate to an augmented reality (AR) system. The AR system includes a projection system and an optical device. The projection system includes a backlight, a lens, and an illumination system. The illumination system is configured to receive light from the backlight and emit light having a first color trend. The light having a first color trend is emitted through the lens towards the optical device. The optical device is configured to form a second color trend. The second color trend is opposite the first color trend.

Abstract: A moissanite ornament, wherein the surface of the moissanite is coated with a diamond film. A method for coating a diamond film on a surface of a moissanite, including: Step 1: performing ultrasonic grinding pretreatment on the moissanite ornament in the nano-diamond powder suspension; Step 2: taking the moissanite ornament out from the nano-diamond powder suspension, and washing clean; Step 3: pressing the moissanite ornament into a preset shape-preserving sample platform to maintain; Step 4: placing, the moissanite ornament together with the shape-preserving sample platform into a diamond film deposition furnace to perform a plasma treatment; Step 5: introducing methane to conduct in-situ diamond film deposition. The moissanite coated with the diamond film on the surface provided by the present disclosure can greatly improve the surface hardness while maintaining the optical properties of the moissanite, thereby improving the scratch resistance performance of the moissanite.
