Previous studies have shown cognition to have an influence on accommodation. Temporal variation in the accommodative response occurs during the fixation on a stationary target. This constantly shifting response has been called accommodative micro-flu

Specimen induced aberrations can have detrimental effects in all types of high-resolution microscope. In this study, we present a sensorless technique that uses a deformable mirror (DM) to correct aberrations of both the system and sample. Using a la

When fixating on a stationary object, the power of the eye’s lens fluctuates. Studies have suggested that changes in these so-called microfluctuations in accommodation may be a factor in the onset and progression of short-sightedness. Like many phy
