Latest Patents

One of his latest patents is titled "Optical scanning for line-of-sight communications to optical tags." This invention involves an optical communication device that emits a series of laser pulses tracing a spiral path over a coverage area. Each laser pulse contains a packet of information modulated at a rate designed to mitigate adverse effects from device movements and scintillation. The configuration of the laser's beam width, scanning speed, and number of pulses increases the likelihood of receiving response pulses with power characteristics that facilitate proper decoding.

Another notable patent is "Modulating retro-reflector optical communication using polarization differential signaling." This invention features a retroreflector coupled with a polarization rotator, which introduces a fraction of a wavelength phase difference in a received beam of light before reflecting it back toward the source. By switching the state of the polarization rotator, a communication signal can be modulated on the return beam of light.
