CORRECTING UNDESIRED DISTORTIONS OR ABERRATIONS AND GENERATING DESIRED WAVEFRONTS IN OPTICAL IMAGING, SENSING, SIGNALING AND OTHER APPLICATIONS BASED ON BI-VALUED WALSH FUNCTIONS

摘要

Devices, systems and techniques are provided for adaptive transformation of wavefronts of optical waves or other electromagnetic waves to either correct the undesirable aberration or provide desirable wavefronts or aberrations for various applications, including imaging, sensing, signaling and other applications.
