Abstract
Official abstract text for this publication.
An alignment method for optical axes of a composite waveplate includes rotating a rotatable waveplate, which rotates about a central axis with respect to a fixed waveplate, and adjusting the rotation angle thereof until the differences between the spectral parameters of the composite waveplate and ideal spectral parameters are smaller than preset values.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for aligning optical axes of a composite waveplate, for any two adjacent waveplates of the composite waveplate, the method comprising: a) fixing a first one of the two adjacent waveplates to be a fixed waveplate and arranging the second one of the two adjacent waveplates to be a rotatable waveplate in parallel to the fixed waveplate and capable of rotating about a central axis with respect to the fixed waveplate; b) vertically irradiating po…
