Latest Patents

Shimada's latest patents include the "Rapid Acoustooptic Tuner and Phase-Shifter." This invention describes the use of a pair of acoustooptic devices in a laser or other optical resonator to produce a wavelength-dependent deflection of light without incurring a net frequency shift. This allows for rapid electronic tuning of the resonator wavelength, as well as quick variations in cavity loss, out-coupling fraction, and round-trip phase shift. The dispersive quality of acoustooptic devices in transmission is utilized as a reflection grating substitute, enhancing the efficiency of laser systems.

Another significant patent is the "Method for Quantifying Optical Properties of the Human Lens." This invention employs fiberoptic, OMA-based instrumentation as an in vivo diagnostic tool for the human ocular lens. It enables rapid, noninvasive assessment of the optical characteristics of a lens using modest levels of exciting light. The method collects backscatter and fluorescence spectra to assess the overall optical quality of the lens, providing metrics that gauge the lens's quality relative to the subject's age.
