Asymptotic analytical modeling of astigmatic rainbow refractometry
None:
We report an asymptotic analytical model for astigmatic rainbow refractometry, synthesized from complex angular momentum theory and the generalized 4D Collins formula. This closed-form solution describes astigmatic wavefront evolution while moving beyond the phenomenological limits of conventional geometric models. The proposed framework elucidates the phase-coupling mechanism behind fringe rotation and characterizes the fine-scale interference ripple structure. These results establish a theoretical foundation for quantitative volumetric diagnostics of complex spray systems.
