Abstract:
1. An observation device for observing an observation object, including an induction factor whose dipole moment changes by induction with an electromagnetic wave, the device comprising: an output part which outputs an electromagnetic wave and changes the dipole moment of said induction factor included in said observation object by the outputted electromagnetic wave; a detection part which detects a signal electromagnetic wave coming through said observation object and a reference electromagnetic wave coming without passing through said observation object among electromagnetic waves outputted by said output part; and an analysis part which analyzes structures of said observation object based on detection result by said detection part; and wherein said electromagnetic wave outputted by said output part is a pulsed laser light which is continuously outputted in pulses; wherein wavelength of said electromagnetic wave outputted by said output part is set to be within an absorption wavelength region of said induction factor causing absorption by said induction factor of irradiated electromagnetic wave; and wherein wavelength of said electromagnetic wave outputted by said output part is set to a value so that absorbance of the electromagnetic wave by said induction factor is beyond a certain lower limit reference level and below a certain upper limit reference level when said induction factor is irradiated with the electromagnetic wave.
