Abstract:
1. A multi-telescope imaging system comprising: a first telescope having a first-telescope input line of sight and a first-telescope ray path. that is incident upon a focal surface imaging location at a first-telescope angle of incidence, wherein the first telescope includes a first-telescope shutter lying on the first-telescope ray path, wherein the first telescope further includes a first-telescope planar backscan-stabilization mirror that is movable opposite to and to negate relative motion of the first telescope and a first-telescope scene viewed by the first telescope, wherein the first-telescope planar backscan-stabilization mirror is pivotable about at least one pivot axis lying in a plane of the first-telescope planar backscan-stabilization mirror; a second telescope having a second-telescope input line of sight and a second-telescope ray path that is incident upon the focal surface imaging location at a second-telescope angle of incidence, wherein the second-telescope input line of sight is not parallel to the first-telescope input line of sight, and wherein the second telescope includes a second-telescope shutter lying on the second-telescope ray path; and a sensor lying at the focal surface imaging location, such that the first-telescope ray path and the second-telescope ray pat are alternatingly incident upon the same focal surface imaging location of the sensor.
