Abstract
The disclosure below is directed to optical/photonic devices and systems configured to control polarization state of light for selective privacy protection in optical imaging. In particular, the various embodiments disclosed below provide an application of polarization manipulation techniques with multiple optical polarization filters to enable partial or full privacy while maintaining functioning of image-based spatial mapping and localization algorithms used in video devices such as virtual reality (VR), augmented reality (AR), and robot/drone cameras. In the disclosed example approaches, the various polarization filters are configured to allow no or negligibly small amount of light from the privacy protected regions of a scene into the cameras in a privacy mode and to reject 100% of all light and enable full privacy in a block mode. The disclosed approaches also dynamically account for orientation changes during operation of the camera devices such that privacy is dynamically protected in real-time.
