  • Publication number: 20200292816
    Abstract: Systems and methods providing optical structures providing a large field of view (FOV) for personal portable displays are described. An optical structure of embodiments comprises a catadioptric optical configuration configured to produce a magnified curved intermediate image, wherein the magnified curved intermediate image is furthered magnified with proper reflection angle and transmitted to viewer's eye. The catadioptric optical configuration may comprise two curved mirrors and a polarization prism. Optical structures comprising such catadioptric optical configurations may utilize relatively small sized image sources to produce a large FOV. Such optical structures are well suited for use in large FOV optical see through (OST) head-mounted displays (HMDs).

  • Patent number: 10754691
    Abstract: An approach is provided in which an information handling system receives a scaling request corresponding to an application that includes multiple workloads executing on a first cloud environment and a second cloud environment. The first cloud environment is managed by a first service provider and the second cloud environment is managed by a second service provider. The information handling system evaluates the scaling request against a first set of policies corresponding to the first service provider and against a second set of policies corresponding to the second service provider. In turn, the information handling system scales, in response to the evaluating, one or more first resources on the first cloud environment and one or more second resources on the second cloud environment to fulfill the scaling request.

  • Publication number: 20200096689
    Abstract: A rotational geometric phase hologram has geometric phase optical elements (GPOEs) serially cascaded along a common optical axis to form a GPOE cascade used for receiving a linearly-polarized light beam and generating output light beams at an exit surface of the last GPOE. Interference occurred in the output light beams creates a polarization interference pattern on the exit surface. A photoalignment substrate, when positioned in close proximity to the exit surface, records the pattern. Advantageously, each GPOE is rotatable about the common optical axis. Respective rotation angles of the GPOEs are determined according to a spatially-varying linear polarization orientation distribution selected to be generated for the polarization interference pattern.

  • Patent number: 10331008
    Abstract: A device for controllably deflecting a first circularly-polarized (CP) light beam from an incident direction with fast response comprises a polarization selector (PS) to adjust the incident light beam's sense of rotation to a desired one to form a second CP light beam, and a polarization grating (PG) to deflect the second CP light beam according to the desired sense of rotation. The PS comprises an optical modulator sandwiched between two quarter-wave plates. The optical modulator has at least one ferroelectric liquid crystal (FLC) half-wave plate (HWP) being reconfigurable in fast axis orientation. The device has a fast response in beam steering due to a short time of reconfiguring the FLC HWP. Based on serially cascading multiple units each being this device, a beam-steering apparatus having fast response and enhanced steering resolution is obtained. The apparatus is usable for enhancing a field of view in projecting an image.
