Currently radio frequencies are employed in wireless internet and cellular telephones. Radio frequencies, however, are partially regulated and can interfere with surrounding devices. In contrast, optical communication offers a non-regulated/cost-effective interface that can be implemented with human safe light sources such as LEDs. Furthermore, the combination of imaging with optical communication makes communication with multiple optical data sources within a scene possible. This thesis explores the design of data communicating imaging sensors that store video and data information from a scene within an array of light sensitive pixels. Applications of these sensors include: security monitoring, optical-based asset tracking, or vehicle-to-vehicle communication. Four data communicating sensor designs are explored, concluding with two key designs: Beta and Gamma. The Beta sensor stores video and data within each pixel. The Gamma sensor stores video in every pixel but distributes data storage among a cluster of pixels. |
