Abstract: Certain aspects pertain to aperture-scanning Fourier ptychographic imaging devices comprising an aperture scanner that can generate an aperture at different locations at an intermediate plane of an optical arrangement, and a detector that can acquire lower resolution intensity images for different aperture locations, and wherein a higher resolution complex image may be constructed by iteratively updating regions in Fourier space with the acquired lower resolution images.

Abstract: Techniques for monitoring cerebral blood metrics such as cerebral blood flow, cerebral blood volume and/or heart rate are provided. In some embodiments, techniques involve a headset with at least one laser configured to emit light into the brain and one or more light detectors such as CMOS sensors that generate information indicative of light reflected from one or more structures within the brain, which can be used to determine the cerebral blood metrics. Each light detector may be positioned within 5 mm of the scalp in some cases.

Abstract: Optical wavefront shaping has been the standard technique to control light through scattering media. Implicit in this dominance is the assumption that knowledge of the optical phase is a necessity for optical control through scattering media. In this paper, we challenge this assumption by reporting on an intensity-only approach for light control through (or reflected from) a disordered scattering medium—optical-channel-based intensity streaming (OCIS). Instead of actively tuning the interference between the optical paths via wavefront shaping, OCIS can control light and transmit information through or from scattering media with linear intensity operation, which not only simplifies and speeds up the system but also enables new applications. We experimentally created focus patterns through scattering media in a sub-millisecond timescale with a phase-manipulation-free setup. We also demonstrate that, unlike wavefront shaping, OCIS can readily generate distinct energy null points through scattering media. Finally, we demonstrate that OCIS enables a scattering medium mediated secure optical communication application.
