Abstract
In certain embodiments, a system may include a housing, one or more lenses, and a scanning system. The housing has an interior region. A lens is disposed within the interior region and transmits a light beam. The scanning system is disposed within the interior region and comprises a number of scanning cells, where each scanning cell comprises an electro-optical (EO) material. The scanning system performs the following for a number of iterations to yield a spot pattern: receive one or more voltages and electrically steer the light beam with the EO material from a current direction to a next direction in response to the voltages.

A system comprising:
- a housing having an interior region;
- one or more lenses disposed within the interior region, each lens configured to transmit a light beam;
- and
- a scanning system disposed within the interior region, the scanning system comprising a plurality of scanning cells comprising a first scanning cell and a second scanning cell, the first scanning cell orthogonal to the second scanning cell, each scanning cell comprising an electro-optical (EO) material, the scanning system configured to perform the following for a number of iterations to yield a laser spot pattern at a plurality of optical fibers:
- receive one or more voltages;
- and
- electrically steer the light beam with the EO material from a current direction to a next direction in response to the one or more voltages.
A system comprising:
- a housing having an interior region;
- one or more lenses disposed within the interior region, each lens configured to transmit a light beam;
- and
- a scanning system disposed within the interior region, the scanning system comprising at least one scanning cell, each scanning cell comprising an electro-optical (EO) material and at least two electrodes, the EO material comprising a polymer-dispersed liquid crystal (PDLC) material, the scanning system configured to perform the following for a number of iterations to yield a laser spot pattern at a plurality of optical fibers:
- receive one or more voltages;
- and
- electrically steer the light beam with the ED material from a current direction to a next direction in response to the one or more voltages.
