<!--StartFragment-->We present an efficient algorithm for determining birefringence in uniaxial crystals using terahertz time-domain spectroscopy (THz-TDS). The method requires only three transmission measurements at specific angular orientations, eliminating the need for full 360° sample rotation required in conventional approaches. It is fully compatible with standard THz-TDS setups and significantly reduces experimental complexity while maintaining high accuracy.<!--EndFragment-->
