Patent ID: 7425694

Claim:
A time-resolved measurement apparatus for acquiring position information and timing information of a quantum beam generated due to excitation of a sample, comprising: a signal generator for generating a reference time pulse in synchronization with the excitation of the sample; a detector for detecting the quantum beam and for generating a position signal corresponding to a detection position, and a detection timing pulse synchronized with a detection timing; a position calculator for calculating the detection position using the position signal; a time difference measuring device for measuring a time difference between the reference time pulse and the detection timing pulse; and a data processor for storing the detection position calculated by the position calculator and the time difference measured by the time difference measuring device, in association with each other, the detector having a position-sensitive electron multiplier tube, the electron multiplier tube having a micro channel plate for generating an electron at a position corresponding to an incidence position of the quantum beam on the electron multiplier tube and for multiplying the electron while maintaining the position, and an output terminal electrically connected to the micro channel plate, the detection timing pulse being generated in response to a potential change that occurs when the electrons multiplied by the micro channel plate are emitted from the micro channel plate, and being fed from the micro channel plate to the time difference measuring device through the output terminal, and the data processor correcting the time difference according to a distance between a position at which the detection timing pulse is generated on the micro channel plate and the output terminal, and storing the corrected time difference in association with the detection position.
