    摘要: An electronic pulse detection device includes: an MCP in which a plurality of capillaries configured to increase the number of electrons are arranged in matrix; and an electronic pulse reading chip 30 disposed on an output side of the MCP. The electronic pulse detection chip 30 includes anodes 32 and detection transistors 34 both provided so as to correspond to the respective capillaries. Electronic pulses are incident on the anodes 32 from the MCP. Drains of the detection transistors 34 are connected to the corresponding anodes. The detection transistors 34 on the same row are connected to one another at gates thereof and turned on/off as a unit, and sources of the detection transistors 34 on the same column are connected to a corresponding switch circuit 80 as a unit to be connected to a current-voltage conversion resistance RL via the switch circuit 80. The current-voltage conversion resistance RL converts a current, which flows therethrough when the electronic pulses are incident on the anodes 32, to a voltage and inputs the voltage to an operational amplifier 90. This makes it possible to detect feeble light and radiation ray two dimensionally.

    摘要: When a flow of a liquid body around a measuring object is visualized, a first liquid body as a tracer is supplied from a nozzle hole into a flow field of a second liquid body, and a laser beam having a wavelength optically absorbed by the first liquid body is irradiated in a manner such that the laser beam traverse across the flow field. At this point, the irradiation position of the laser beam is controlled in such a manner that the flow field is scanned with the laser beam. On the other hand, the laser beam that has passed through the flow field is received and a position where the first liquid body traverses the laser beam is obtained using the scan intensity signal of the received laser beam so that the flow of the second liquid body is visualized. The position where the first liquid body traverses the laser beam can be obtained based on a position on a time axis where a value of the scan intensity signal is less than a set threshold. According to the above described visualization, the flow field can reliably be visualized even for the high-speed fluid body.

    摘要: A weak light detector (40) which can detect two-dimensional weak radiation at a high speed with high precision. The fluorescence from the DNA chip (46) is incident on a detection part (56) of a detection unit (52). The detection unit (56) has a detection module with a number of detection transistors being placed to correspond to cells of the DNA chip (46). The detection part (56) performs photoelectric conversion of the incident fluorescence (photon) to emit electrons, and amplifies the electrons to make them incident on the detection module. The detection transistors are switched based the Hadamard matrix to operate. A data processing unit (54) reads an output signal of the detection part (56), then performs Hadamard inversion, and determines the detection transistor which outputs the signal.

    摘要: A liquid sample flow containing living cells is irradiated with measurement laser light and the photo data of at least either scattering light or fluorescence that is generated by each of the living cells in the liquid sample flow due to the irradiation with the measurement laser light is acquired. Based on the photo data thus acquired, it is determined whether each of the cells assignable to the respective photo data is an unnecessary living cell or a target living cell. Based on the determination results, a pulse voltage is then applied exclusively to the living cells having been determined as unnecessary living cells so that the unnecessary living cells are damaged and killed.
