In a multimode or multispectral electromagnetic detection system (11), a pair of rotatable scanning prisms (13' and 13"), each of said prisms comprising at least a pair of cooperative subprisms (13'a, 13'b, 13"a and 13"b), and the cooperative materials of the subprism being selected so as to ensure that electromagnetic radiation passing through the pair of rotatable prisms is equally deviated in a transverse direction.

A radar antenna arrangement with at least a pair of feeds, said arrangement including a corresponding at least a pair of lens elements, the element closest to said feeds effective for collimating the output beam of each of said feed, and the remaining ones of said elements each being associated with a different one of said feeds, whereby at least a pair of separate antenna beams are capble of projection toward a target region.

A multimode, multispectral antenna system (14) for detecting radiation from selected target regions in each of at least a pair of selected spectrum bandwidths through collimating lens (35), and rotatable, cooperative prisms (21) effective for collimating and scanning beams of radiation controllably with respect to said target regions.

H01Q 1502

343754

A method of constructing rotatable scanning prisms (13' and 13") for a multimode detection system (13), each including first and second subprisms (respectively 13'a, 13'b and 13"a, 13"b); the method including the steps of chosing an apex angle for one of said subprisms, determining therefrom apex angles at first and second wavelengths for each of said subprisms, and evaluating whether the differences of apex angles at said several wavelengths are acceptably small.

An optical system having a spherical mirror is used to collect light from the surface of a turbine blade or the like which is to be contoured. The spherical mirror is located at an equal optical distance from both the test specimen and the linear diode array so that it operates at a one-to-one magnification ratio. The linear diode array is positioned behind the spherical mirror and it receives light focused by the mirror and reflected by a beam splitter through an opening in the center of the mirror. None of the optical elements of the inspection system are located in the plane of movement of the test specimen so that even particularly long items such as a helicopter rotor blade can be contoured. Indentical upper and lower optical systems allows both surfaces of the test specimen to be contoured simultaneously and each system is independently operable and oriented to prevent optical interference. An automatic gain control is provided to adjust the optical modulator so that the effective intensity of the spot presented to the diode array is maintained within predetermined limits.
