Perceived Transverse Chromatic Aberration study, published in Biomedical Optics Express

We implemented a new channel in a polychromatic Adaptive Optics system to measure Transverse Chromatic Aberration (TCA). Perceived TCA (measured with a large pupil) differs from optical TCA (measured with a small pupil). Besides, correcting monochromatic aberrations changed TCA orientation and increased its magnitude. We found that estimations of perceived TCA considering measured optical TCA, Stiles-Crawford Effect, Monochromatic Aberrations and Longitudinal Chromatic Aberration accurately predicted the measured perceived TCA. The study allows therefore understanding the relative contributions of different factors to polychromatic chromatic image quality.
