Abstract: In an optical measurement device, in a first process, a reference member is irradiated with excitation light, light for a calibration process including scattered light associated with the excitation light from a reference member is detected as detection light, a calibration signal corresponding to the light for the calibration process is designated as a detection signal, and a calibration process for removing a signal component corresponding to the scattered light from the detection signal in a second process is performed. Also, in the optical measurement device, in the second process, a sample is irradiated with the excitation light, measurement target light including fluorescence generated from the sample and light scattered from the sample irradiated with the excitation light is detected as detection light, and a signal component corresponding to the scattered light from a measurement signal.

Abstract: An optical measurement device includes an irradiation optical system, a detection optical system, and a cancel circuit. In a fluorescence detection process, a sample is designated as an irradiation target, the sample is irradiated with irradiation light, measurement target light including fluorescence generated from the sample irradiated with the irradiation light and light scattered from the sample irradiated with the irradiation light is detected as detection light, a signal component corresponding to the scattered light is removed from a measurement signal corresponding to the measurement target light in consideration of a result of performing a calibration process during a preliminary process. In the preliminary process, the calibration process for removing a signal component corresponding to the scattered light from the measurement signal is performed on the basis of a calibration signal having a higher signal intensity than a signal corresponding to the scattered light in the measurement signal.

Abstract: An optical measurement device includes a light detection element for detecting detection light including fluorescence generated from an immuno-chromatography test piece irradiated with excitation light and scattered light caused by the excitation light and having a phase equivalent to that of the excitation light, and a cancel circuit for processing a detection signal corresponding to the detection light. The cancel circuit removes a signal component corresponding to the scattered light from the detection signal on the basis of a phase difference between the fluorescence and the scattered light.

Abstract: The pair of vertical deflection electrode plates 13 in the double sweeping streak camera are supplied with a voltage of a sawtooth wave in synchronization with the input optical beam pulses. The other pair of horizontal deflection electrode plates 14 are supplied with a voltage of a stepped wave in synchronization with the sawtooth wave. The deflection electrode plates 13 and 14 sweep successively-incident photoelectrons. The photoelectrons are then detected at the phosphor screen 16. The phosphor screen 16 is therefore recorded with temporal changes in the spatial pattern of the optical beam pulse as an image of regularly-arranged optical beam patterns. The image analyzing device can easily analyze the image.

Abstract: A step voltage generator for outputting a step voltage from an output terminal. The step voltage generator includes a voltage dividing circuit having a plurality of dividing elements serially connected to each other and disposed between two power sources of different voltage levels for voltage dividing the potential difference between the two power sources. The step generator further includes a switching circuit having a plurality of switch devices serially connected to each other and similarly disposed between the two power sources. The end switch device of the serially connected bunch is connected to the output terminal. A trigger circuit turns on the switch devices sequentially starting with the one closest to the output terminal. A plurality of reverse flow preventive circuits prohibit current through a switch device most recently turned on from flowing through a voltage dividing element previously turned on and which remains on.
