Publication number: 20240114223Abstract: A camera assembly with two distinct magnifications is described. The camera assembly includes a lens assembly with two modules to perceive light. The first module includes two halves of different lens assemblies disposed together to provide two different optical paths and fields of view to obtain the two different optical magnifications. The second module includes a lens assembly common to the two halves of the first module. A biprism provides light separation for the two halves of the first module. Thus, light received and subjected to two different magnifications in the first module at a distal end of the camera assembly is further processed through the second module before being provided to a sensor. The biprism at the camera's distal end keeps the two different lens assemblies of the first module at the same viewing direction.Type: ApplicationFiled: March 16, 2023Publication date: April 4, 2024Applicant: Meta Platforms Technologies, LLCInventor: Dongmin YANG

Publication number: 20240027722Abstract: A flat-surfaced, electrically controlled, tunable lens to provide autofocus, optical zoom, optical image stabilization, and similar functionalities is described. A thickness profile of the tunable lens may be modified through a voltage-controlled thin film piezo actuator, for example, a lead-zirconium-titanium oxide (PZT) film. For autofocus and optical zoom features, an entire thickness of the tunable lens may be modified with the thickness being the same across a cross-section area of the tunable lens and opposing surfaces of the tunable lens remaining flat. For optical image stabilization, the thickness profile of the tunable lens may be modified to a tilted profile, where one side of the tunable lens is thinner than the other side with the opposing surfaces of the tunable lens remaining flat. The tilted profile may have an angle between the two plates (surfaces) in a range up to 10 degrees.Type: ApplicationFiled: January 5, 2023Publication date: January 25, 2024Applicant: Meta Platforms Technologies, LLCInventors: Dongmin YANG, Fei Liu
