Abstract

Described are a vehicle optical communications system and network to exchange high bandwidth optical data between vehicles or between a vehicle and a stationary host. The vehicle optical communications system includes a communications module and a sensor having pixels for detecting an image in a field of view. Each pixel can generate a pixel data signal responsive to an incident optical data signal that includes vehicle data transmitted from a remote optical transmitter. The communications module provides remote data in response to the pixel data signals. The vehicular communications system optionally includes an optical transmitter to enable bi-directional communication. Data can be transmitted through a multi-node network of vehicular communication systems deployed in vehicles or on stationary hosts located between or around the data transmitter and intended data receiver. Simultaneous data from multiple optical transmitters within the sensor field of view are processed concurrently and maintained as separate communication channels.

Dependent claims

A vehicular optical communications network, comprising:

a vehicle optical transmitter for generating a vehicle optical data signal comprising vehicle data;
a vehicle sensor having a plurality of pixels and detecting an image in a vehicle sensor field of view, each pixel configured to generate a pixel data signal responsive to a remote optical data signal if a remote optical transmitter is in a respective pixel field of view;
a vehicle communications module in communication with the vehicle sensor, the vehicle communications module generating a data signal responsive to the pixel data signal generated by at least one of the pixels of the vehicle sensor;
a remote optical transmitter for generating a remote optical data signal comprising remote data;
a remote sensor having a plurality of pixels and detecting an image in a remote sensor field of view, each of the pixels of the remote sensor configured to generate a pixel data signal responsive to the vehicle optical data signal if the vehicle optical transmitter is in a respective pixel field of view;
and
a remote communications module in communication with the remote sensor, the remote communications module generating a data signal responsive to the pixel data signal generated by at least one of the pixels of the remote sensor.
