Abstract
We expand the effective size of the eyebox of a magnified telescopic weapon sight by following the movements of the operator’s eye to create a larger, ‘electronic eyebox’. The original eyebox of the telescope is dynamically relocated in space so that proper overlap between the pupil of the eye and the exit pupil of the device is maintained. Therefore, the operator will perceive the entire field of view of the instrument in a much bigger spatial region than the one defined by the original eyebox. Proof-of-the-concept results are presented with a more than 3.5X enlargement of the eyebox volume along with recommendations for the next phase of development.
