Abstract
An imaging subsystem is disclosed, wherein the imaging subsystem is coherent and it generally includes an optical phased array (OPA), frequency modulation (FM) and/or amplitude modulation (AM). The imaging subsystem is operable with a Super System on Chip (SSoC) or a photonic neural learning processor (PNLP). The Super System on Chip (SSoC) includes memristors. The imaging subsystem is further operable with a camera (e.g., a metamaterial camera, wherein the metamaterial camera includes one or more metasurfaces). Furthermore, the imaging subsystem may be included with a vehicle system, wherein the vehicle system can recommend a service or an offer to a user/driver by anticipating any need of the user/driver.
