Latest Patents

Stensby holds a patent for a "Modulated High Sensitivity Infrared Polarimeter." This invention involves producing a modulated Faraday rotation signal by passing a linearly polarized laser beam through a semiconductor wafer sample. The process is enhanced by a modulated magnetic field induced in an electromagnet, which is controlled by a sine wave generator and driver. The rotation signal is normalized by dividing it by a transmission signal, which is produced by modulating the beam with a chopper operating at a different frequency. This method results in a Faraday rotation measurement characterized by a high signal-to-noise ratio and compensation for laser drift in intensity.
