  • Optical microscope and optical instrumentation
    Patent number: 9109954
    Abstract: An optical microscope that can prevent an increase in the complexity of the light source system is equipped with optics readily capable of adequate operation even when the modulation frequency is increased to reduce the impact of the intensity noise of the laser. The optical microscope irradiates a sample with a first train of optical pulses having a first optical frequency, which is generated by a first light source, and a second train of optical pulses having a second optical frequency, which is temporally synchronized with the first train of optical pulses and is generated by a second light source, and detects light scattered from the sample. A first repetition frequency of the first train of optical pulses is an integral sub-multiple of a second repetition frequency of the second train of optical pulses.

  • Optical microscope and optical instrumentation
    Patent number: 8629980
    Abstract: The invention provides an optical microscope that prevents an increase in the complexity of the light source system and is equipped with optics readily capable of adequate operation even when the modulation frequency is increased in order to reduce the impact of the intensity noise of the laser, etc. This optical microscope 100 irradiates a sample 6 with a first train of optical pulses having a first optical frequency, which is generated by a first light source, and a second train of optical pulses having a second optical frequency, which is temporally synchronized with the first train of optical pulses and is generated by a second light source, and detects light scattered from the sample 6. The repetition frequency of the train of optical pulses generated by the first light source is an integral sub-multiple of the repetition frequency of the train of optical pulses generated by the second light source.

  • Method for introducing foreign matters into living cells
    Patent number: 7132289
    Abstract: A method for introducing a foreign matter into a cell, includes the steps of placing a small particle carrying a foreign matter at a part of a cell surface of a living cell, boring a hole in a cell wall and/or a cell membrane by irradiating and treating said part of the cell surface with a laser beam, and introducing the foreign matter into the living cell.
