Latest Patents

Among Hara's latest inventions are groundbreaking patents related to luminescence lifetime measurement. One notable patent describes an apparatus designed to measure luminescence lifetime through simultaneous operation of two sets of Time to Amplitude Converters (TACs). This innovative approach utilizes a start pulse to trigger both sets, capturing photoelectron pulses from an excited sample and its subsequent fluorescence. Each TAC generates a voltage representative of the interval between start and stop pulses, allowing for concurrent measurement of excitation light shape and luminescence transience. This technology culminates in a two-picture synthetic display showcasing both measurements, providing clearer insights into luminescence dynamics.

Additionally, Hara has developed a method for creating time-resolved emission and excitation spectra. By employing the time correlation photon counting method, this technique accurately captures emission transient waveforms at optimal wavelengths across the emission spectrum. The data is systematically stored and analyzed, leading to the efficient production of high-quality time-resolved emission and excitation spectra.
