Modulations of face perception in response to a novel time-varying optical perturbation after aberration correction using adaptive optics

The role of time in the perception of optical perturbation has received little attention. We sought to establish a novel time-varying perturbation in an image sequence using adaptive optics. We introduced the interpolated blur as a probe of visual processing, including four originally identical image frames whose position and pattern were manipulated to transform the time-averaged aberration. The resulting effects of interpolated blur were measured by comparing the dynamic sequence with the reference stimulus under the same condition of time-averaged aberration. Our results demonstrated that the perception of the time-averaged aberration depends on the optical perturbation, suggesting the potential modulations of interpolated blur on the correction of spatial blur. Our findings provide an entry point to implement adaptive optical correction to investigate dynamic changes of interpolated blurs.
