Latest Patents

Hirano holds a patent for a device and method for measuring optical constants. This invention involves a coherent light source that outputs coherent light, including high-order harmonics obtained by irradiating short-pulse laser light to a nonlinear medium. The spectrometer in his invention includes a grating that diffracts the coherent light and an image sensor that measures an image of the diffracted light. In the first state, a first double slit with a pair of apertures is arranged at a predetermined position between the coherent light source and the incident slit of the spectrometer. In the second state, a second double slit, which is a replica of the first, is arranged at the same position, replacing the first double slit with a sample held in one aperture. A calculation processing device then calculates the optical constants of the sample based on interference images measured in both states. Hirano has been granted 1 patent for this innovative technology.
