Publication number: 20110266462Abstract: When a fluorescence relaxation time of a fluorochrome is determined using a measurement object obtained by attaching the fluorochrome to an analyte, a first laser beam is intensity-modulated by a modulation signal with a frequency of f1 and a second laser beam is intensity-modulated by a modulation signal with a frequency of f2. A first fluorescent signal and a second fluorescent signal are obtained. The first fluorescent signal is mixed with the modulation signal with a frequency of f1 to produce first fluorescence data P1, and the second fluorescent signal is mixed with the modulation signal with a frequency of f2 to produce second fluorescence data P2. The fluorescence relaxation time is calculated using fluorescence data obtained by subtracting the result of multiplication of the second fluorescence data P2 by a second constant from the result of multiplication of the first fluorescence data P1 by a first constant.Type: ApplicationFiled: January 4, 2010Publication date: November 3, 2011Applicant: MITSUI ENGINEERING & SHIPBUILDING CO., LTDInventor: Kyouji Doi

Patent number: 8049185Abstract: In a fluorescence detection device and a fluorescence detection method, forward-scattered light which is scattered from a measurement object irradiated with a laser beam is received and detection signals for informing the measurement object passing through the measurement point and for identifying a focus position of the forward-scattered light are produced. While, fluorescence emitted by the measurement object is received through a collecting lens and a light-reception signal of the fluorescence is outputted. The fluorescence intensity level is outputted based on the outputted light-reception signal and the produced detection signals. A focus position of the forward-scattered light is identified from the produced detection signals and the light reception-signal is corrected using a correction coefficient corresponding to the identified focus position.Type: GrantFiled: February 4, 2009Date of Patent: November 1, 2011Assignee: Mitsui Engineering & Shipbuilding Co., Ltd.Inventors: Hironori Hayashi, Shigeyuki Nakada
