Measured PSF as a Function of Curvature

For each curvature of the lens array, we raster scanned a small bright dot on the LCD monitor above the apparatus. As this dot was scanned, we measured the brightness of the spot on the diffuser produced by the central lens of the array. The measured brightness values are used to plot the object side PSF of the central lens. As seen this figure, the measured PSF increases in width as the local curvature increases, demonstrating that the FOV of the lens does indeed increase with curvature to mitigate image aliasing.
