摘要 |
<p>A time domain polarization analyzing apparatus that is able to derive the complex optical constant spectrum in the terahertz region of a sample without necessitating any reference measurement will be proposed. The polarization analyzing apparatus of the present invention has: a light source for generating optical pulses; a light dividing part for dividing optical pulses emitted from the light source; an electromagnetic wave radiation part for inputting one of divided optical pulses and radiating electromagnetic wave; a collimation part for collimating the radiated electromagnetic wave; a polarizer part for inputting the collimated electromagnetic wave and letting polarized electromagnetic wave pass therethrough, and also capable of switching over its polarization plane; a light analyzer part for inputting the polarized electromagnetic wave reflected from a sample and letting the polarized electromagnetic wave component pass therethrough; a condenser part for condensing the passing polarized electromagnetic wave component; an optical time-delay part for variably causing a time-delay in the other divided optical pulses; and an electromagnetic wave detector part for inputting the condensed polarized electromagnetic wave component and the time-delayed optical pulses and converting the condensed polarized electromagnetic wave component into an electrical signal. <IMAGE></p> |
