Optimal field mappings that provide the highest contrast images for back-scanned and time delay integration (TDI) imaging are given. The mapping can be implemented for back-scanned imaging with afocal optics including an anamorphic field correcting assembly configured to implement a non-rotationally symmetric field mapping between object space and image space to adjust distortion characteristics of the afocal optics to control image wander on a focal plane array. The anamorphic field correcting assembly can include one or more mirrors or lenses having non-rotationally symmetric aspherical departures. For optimal TDI imaging, anamorphic optics are also employed.

An optical imaging assembly is provided, having an optical axis; an object axis defined by an object being imaged; an aperture stop disposed on the optical axis; a light-transmissive sleeve enclosing the object axis, being disposed in object space defined by the object axis; and at least three refractive lens elements being arranged between the object and the aperture stop without any other intervening optical component, at least one of the elements having surfaces having at least one of cylindrical and acylindrical prescription, with an image plane, wherein the object being imaged lies within the sleeve.

An elongated laser beam optical assembly. The assembly has a laser light source that produces a laser beam. A cylindrical anamorphic lens has a planar surface at a first end and an anamorphic surface at a second end thereof, the first end receiving the laser beam from the laser light source and producing an output laser beam from the second end thereof. An aperture passes the output laser beam from the second end of the anamorphic lens to produce an elongated laser beam.
