Optical Perturbers#

Optical perturbers simulate physics-based sensor and optical effects using the pyBSM (Python-based Sensor Model) library. These perturbations model real sensor behavior, aperture characteristics, and optical phenomena to support realistic, sensor-driven robustness evaluations. For detailed information about pyBSM concepts and parameters, see the pyBSM documentation.
