Paper Abstract

A tunable mid-wave infrared Mueller matrix scatterometer was recently developed. Initial design efforts were directed at using existing non-achromatic retarders and leveraging the flexibility of the measurement matrix method for dual rotating retarders. However, insufficient retardance existed among the non-achromatic retarders (~λ/5 at 4.35μm), resulting in high condition numbers and large errors in free-space Mueller matrix extractions. Condition number analysis and random error analysis was applied to the measurement matrix method and led to the selection of achromatic λ/3 retarders in the final design. This establishes a near-optimum configuration and the opportunity to develop and test measurement matrix method calibration techniques.
