Filed: 2003-03-20
Abstract: <P>PROBLEM TO BE SOLVED: To cope with a change in a cycle period of waveform of a light signal and to simply structure the whole of a system.  <P>SOLUTION: A calculation means 22 calculates a sampling period different from an integral multiple of the cycle period of the light signal P by offset delay time based on information designated by a parameter designation means 21 and causes a clock signal C having the calculated sampling period to be outputted from a signal generation means 23 to a light sampling pulse generation means 24 to cause the light signal P to be sampled by means of light sampling pulses Ps having the sampling period. A pulse signal Eo outputted from a light sampling part 25 is A/D converted in the period of the clock signal C. A fundamental wave constituent signal Q of the pulse signal Eo is stored in a waveform data memory 35 from when the signal Q exceeds a preset threshold V in a prescribed direction, and the waveform data are read out and waveform-displayed on a display 37.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
