Abstract: An imaging method and system are provided, being particularly useful for imaging a relatively wide field of regard on a relatively small detection surface with high spatial resolution. The method comprises: creating a segmented image of a field of regard in an effective object plane, said image being formed by an array of N image parts of the field of regard; and projecting a selected number M≧1 of patterns of structured light onto a detection surface, which is located in a plane conjugate to the effective object plane and has geometry and size substantially of the image part, each of the M patterns being formed by selected K light components of said N image parts concurrently projected onto the entire detection surface forming a superposition of the K image parts, thereby enabling reconstruction of the image of the field of regard from detected number M of patterns of the structured light.
