Abstract :
The optical constants, birefringence and dichroism of liquid crystals BL037 and GT3-23001 are investigated in the frequency range 0.4-4 THz using time-domain spectroscopy. A specially designed bias cell is described which allows the orientational dependence of optical properties to be observed.
