For Visual ID and LiDAR that can be used for AR and VR applications, today the US Patent & Trademark Office released a patent application from Apple related to devices such as iPhones and MacBook Pro with glass ceramic area new built into the camera area which can positively affect the transmission of light to or from the optical components within the enclosure.
At Apple’s patent office they noticed that there are many portable electronics today with cameras and many optical sensors integrated into the device. Normally, cameras or other optical sensors are located under the sheet of glass cover or plastic component of the enclosure. The current patent application is a guide to electronic enclosures that include glass ceramic materials and may have advantages as compared to some traditional electronic enclosures.
Electronic enclosures include a glass ceramic area in the optical sensor area or optical component, which can be specifically designed to enhance the sensor performance and / or visual acuity of the device.
Apple design with cover member and glass ceramic area can be formed in the cover member. The glass ceramic area may have different opals or other properties as compared to other areas of the cover member.
For example, another area of the cover member could be a glass area or a glass ceramic area with different glass ceramic materials. The glass ceramic area may also have optical properties or optical properties that are different from other environments. For example, a ceramic glass area may have a moving or pointed arrow that is different from that of another area.
Optical components can be configured to illuminate or detect light in a range of specific lengths. In some cases, the ceramic glass area may be configured to have less transmission for light at an isolated length than other area of the cover member.
