Latest Patents
One of Erickson's latest patents is a "Multiplexed laser interferometer for non-dispersed spectrum detection." This invention involves two laser sources of different frequency monochromatic light that are time-multiplexed through a beam combiner. The composite beams are directed to a gap between a slider and a disk, where reflected light containing an interference pattern is detected by a photodiode. This method allows for precise measurements of the slider to disk spacing by comparing the intensities of the different frequency lights. An alternative embodiment includes multiple photodiode detectors for simultaneous assessment at various points.
Another significant patent is a "Method of making a mirror having extremely small aperture holes." This process involves notching the backside of a glass plate and etching it to create mirrors with finely formed aperture holes. The technique utilizes a bundle of fused glass rods, where one rod is susceptible to etching, allowing for the creation of precise holes of desired diameters.
