Abstract
Methods for compensating measurements of devices under test (DUTs) captured through prescription lenses (and associated imaging systems, devices, and methods) are described herein. In one embodiment, a method for characterizing focus quality of a DUT through a prescription lens includes adjusting an optical power of a measurement device to compensate for optical power provided by the prescription lens. The method further comprises imaging, using the measurement device, a test pattern through the prescription lens, wherein the test pattern is displayed by the DUT; measuring contrast of an edge in the test pattern at a point of interest within the imaging of the test pattern; and determining focus quality of the DUT based at least in part on the contrast measurement.
