Design and Alignment Strategies of 4f Systems used in the Vectorial Optical Field Generator
In this paper, the design and alignment strategies of 4� systems used in the vectorial optical field generator are described in detail. Reflection-type 4� systems were adopted due to limited spacing. Alignment patterns are designed and introduced as alignment tools so that the optical property (degree of freedom) controlled by each specific spatial light modulator section can be visualized and alignment of the 4� systems can be performed using the CCD image sharpness as the metric. In particular, blurring due to diffraction effects is minimized when the 4� system is fully aligned.
