Abstract: An optical lens assembly with an electrically controlled, tunable optical lens with an attached aperture stop provides autofocus or similar functionalities in a camera with a wide field of view (FOV) (that is larger than 100 degrees in diagonal direction). The tunable optical lens is positioned between a first optical lens and a second optical lens in the optical lens assembly with the assembly including any number of negative or positive optical power lenses and/or other optical elements such as polarizers, quarter wave plates, optical filters, and similar ones. An optical profile of the tunable optical lens is modified through a voltage-controlled thin film piezo actuator based on a determined focus distance.

Abstract: In one embodiment, a system includes a silicone hemispherical dome and an omnidirectional optical system. The dome includes a surface including a reflective silver-film layer. The optical system includes a lens including multiple lens elements with the first lens element in direct contact with the hemispherical dome without airgap. The lens is configured to capture scattering of internal incident light generated by the reflective silver-film layer. The optical system also includes an image sensor configured to generate image data from data captured by the lens. The system also includes non-image sensors. The system further includes processors and a non-transitory memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to access the image data from the omnidirectional optical system and sensing data from the non-image sensors and generate touch digitization based on the accessed image and sensing data by machine-learning models.
