An improved phase modulated technique has been implemented to increase the speed and accuracy of optical parameters extraction for a uniaxial bulk media. In combination of the genetic algorithm, we show that not only the complex refractive indices, the inclination and azimuth angles of optical axis can also be extracted. Furthermore, by using a two-probe-beam configuration, the speed of convergence can be improved by 5-times. Such a high speed and accurate method can be applied for the in-situ measurement of dynamic materials.
