The precise detection and alignment methods of the birefringent axes are critical techniques for the application of the polarization maintaining (PM) fibers. In this paper a new method is presented to observe the birefringent orientation of the PANDA fiber by use of the TV microscope when the optical fiber is ilimuinated by a transverse collimated beam. The formation mechanism of the birefringent orientation image and its observed condition is analysed by use of the ray tracing method. The computer simulated results are in agreement with the practical observed results.
