While laser pulse is being transferred through the optical cable, parts of an anti-stokes line and a stokes line are returned to the opposite direction of the pulse proceeding direction. The anti-stokes line and the stokes line passing through optical filters(40) are separated and are converted into electric signals through opto-electric converters(50). The electric signals are stored in a memory by passing through an electronic circuit section(60) connected to a computer(70).
