A fluorescence detecting device irradiates an object to be measured with a laser beam, receives fluorescence generated from the object and processes a fluorescence signal generated when receiving the fluorescence. The device includes a laser light source section outputting the laser beam for irradiating the object, a light receiving section outputting the fluorescence signal of the fluorescence generated by the irradiated object, a light source control section generates a modulation signal having a frequency in order to time-modulate an intensity of the laser beam, and a processing section that calculates a fluorescence relaxation time of the fluorescence of the object based on the fluorescence signal output from the light receiving section. From the detection values acquired by the device including the phase information on the fluorescence, the intensity of the fluorescence is calculated.

Fluorescence detecting device and fluorescence detecting method

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 chipdisposed on an output side of the MCP. The electronic pulse detection chipincludes anodesand detection transistorsboth provided so as to correspond to the respective capillaries. Electronic pulses are incident on the anodesfrom the MCP. Drains of the detection transistorsare connected to the corresponding anodes. The detection transistorson the same row are connected to one another at gates thereof and turned on/off as a unit, and sources of the detection transistorson the same column are connected to a corresponding switch circuitas a unit to be connected to a current-voltage conversion resistance Rvia the switch circuit. The current-voltage conversion resistance Rconverts a current, which flows therethrough when the electronic pulses are incident on the anodes, to a voltage and inputs the voltage to an operational amplifier. This makes it possible to detect feeble light and radiation ray two dimensionally.
