The Fizeau’s light birefringence dragging effect is investigated in a moving chiral medium. The effect significantly influences the subluminality, superluminality, phase shift and divergence angle between the circularly polarized birefringent modes. The maximum superluminal group velocity is measured in the range \(-4\times 10^8\)–\(1\times 10^{10}\)m/s. The group index and group velocity measured with phase of the control field and phase of the superposition states are in the range \(0.4\le n^{(\pm )}_g\le 0.8\) and \(4\times 10^8\)m/s\(\le v^{(\pm )}_g\le 8\times 10^8\)m/s, respectively. The maximum Fizeau’s birefringence dragging coefficient is noted in the range \(-20\le F_D\le 20\) and varies with phases of the applied fields in the range \(\pm 1\). The birefringent phase uncertainty between the phase shift under dragging and in the absence of the dragging effect is in the range \(0.005\le \Delta \Phi ^{(\pm )}\le 0.015\) radian. The divergence angle between the two modes is in the range \(0.000\le \theta _d\le 0.004\) radian. The controlled birefringence phase uncertainty may show significant applications in interferometry, velocimetry and sensitivity.

在移动的手性介质中研究了Fizeau的光双折射拖动效果。该效应显着影响圆偏振双折射模式之间的亚光度，超光度，相移和发散角。最大超腔群速度的测量范围为\（-4 \乘以10 ^ 8 \） – \（1乘以10 ^ {10} \） m / s。用控制场的相位和叠加状态的相位测得的组索引和组速度在\（0.4 \ le n ^ {（\ pm）} _ g \ le 0.8 \）和\（4×10 ^ 8 \） m / s \（\ le v ^ {（\ pm）} _ g \ le 8 \ x 10 ^ 8 \） m / s。最大菲索双折射系数记在\（-20 \ le F_D \ le 20 \）范围内并随所应用字段的相位在\（\ pm 1 \）范围内变化。在拖动下和没有拖动效果的情况下，相移之间的双折射相位不确定性在\（0.005 \ le \ Delta \ Phi ^ {{（\ pm）} \ le 0.015 \）弧度的范围内。两种模式之间的发散角在\（0.000 \ le \ theta _d \ le 0.004 \）弧度范围内。受控的双折射相位不确定性可能在干涉测量，测速和灵敏度方面显示出重要的应用。
