Light field display metrology

An optical metrology system for performing image correction on a display, the system comprising:

• a camera configured to capture an image projected by a display;
• a hardware processor programmed with executable instructions to:
• generate a vector field based at least partly on the image captured by the camera, the vector field comprising vectors corresponding to deviations between projected positions and expected positions of points of the display;
• and
• calculate, based at least partly on the vector field, at least one of:
• a centration correction, an aggregate rotation correction, an aggregate scaling correction, or a spatial mapping, for the display;
• calculate, based at least partly upon the image captured by the camera, values associated with the luminance of a plurality of points on the display;
• and
• calculate, based at least partly on said determined values, a luminance flattening correction or a chromatic balancing correction, for the display.
