Latest Patents

Taliaferro holds a patent for a "Polarimeter with multiple independent tunable channels and method for material and object classification and recognition." This invention discloses embodiments of an active or laser polarimeter that transmits multiple independent and tunable temporally-multiplexed polarization states. It records or images the polarized intensity or irradiance reflected or transmitted by objects illuminated by those states. The recorded data is then applied to material and/or object classification and recognition using classification algorithms that exploit features of polarization signatures dependent on material type, texture, and/or object shape. The polarimeter also records and utilizes one or more passive polarization measurements to realize a hybrid active-passive polarimeter.

The channels of the polarimeter are configured and tuned to access multi-dimensional signature spaces specified by existing signature models and/or measurements. The polarization-modulator settings are derived by a newly-disclosed subspace-projection algorithm that maximizes a target contrast parameter. This innovative design allows the new polarimeter to outperform conventional two-channel polarimeters while minimizing sensor size, weight, and power (SWaP) and maximizing speed.
