The invention relates to a real time measuring device and a method thereof for the orientation of a fast axis of a quarter wave plate. The device consists of a collimated light source, a polarizer, a standard quarter wave plate, a diffraction light splitting element, a focusing lens, a ...
A wave plate is a device used to control the polarization of light. When light is polarized, it is directed in two axes; the angle between the axes, one being designated the fast axis and the other the slow axis, is 45°. A quarter-wave plate transforms linearly polarized light into ...
Thorlabs' Zero-Order Quarter-Wave Plates are built by combining two Multi-Order Crystalline Quartz Wave Plates to obtain an optical path length difference of λ/4. By aligning the fast axis of one plate with the slow axis of the other, the net result is a compound retarder whose exact reta...
2) λ/4 wave-plate λ/4波片 1. The results indicate any elliptically polarized light can be compensated to become lineally polarized light throught λ/4 waveplate as long as the fast-axis(slow-axis) of λ/4 wave-plate and the long-axis(short-axis) of elliptically polarized light ...
Compound Zero-Order Waveplate, also called compound waveplate, is to glue two multi-order waveplates together, by aligning the fast axis of one waveplate and the slow axis of the other waveplate for use. The full-wave...
1.A quarter wave plate (QWP) is frequently used in a pulse Nd : YAG laser resonator and its function is determined by its location and the direction of the fast axis in the resonator.1/4波片在Nd:YAG激光器谐振腔内有多种应用,其作用由其在谐振腔内的位置和快轴方向决定。 4)quarter-wavepl...
A waveplate has a slow axis and a fast axis, both being perpendicular to the beam direction, and also to each other. The phase velocity of light is slightly higher for polarization along the fast axis. The designed value of optical retardance (difference in phase delay for the two ...
A novel method used for the enhancement of the accuracy of the retardance measurement of a quarter-wave plate employing two polaroids and a prism is reported under the condition of knowing the direction of the fast-axis of the plate. The theoretical analysis of the principle and the uncertainty...
