Abstract:
1. An imaging system for imaging a range of field points over on- and off-axis fields, the imaging system comprising: an image sensor for capturing image data, the image sensor including a cover glass; a first substrate supporting a first optical element; and a second substrate supporting a second optical element, the second substrate being separated from the first substrate by a spacer; wherein the first and second optical elements are capable of forming an image at the image sensor utilizing only the first and second optical elements, and wherein the first and second optical elements are configured for jointly modifying a phase of the light transmitted therethrough such that point-spread functions (“PSFs”) corresponding to the range field points are substantially uniform over on- and off-axis fields, and wherein the substantially uniform PSFs from the transmitted light are achieved through interaction of only the configured first and second optical elements.
