Abstract: A camera concurrently produces an orthographic map and map spectral content. Illumination from an image passes through a phase modulator and the resulting rotating photo-flux phase is converted to an electrical signal by multiple adjacent sensors of detectors of array of detectors. The amount of unwanted illumination reaching the sensors is reduced by a set of baffles that shield and protect the transducers from unwanted out-of-field light and other light sources.

Abstract: A scope correction apparatus comprises at least one lens and is positioned on a weapon in front of a reticled scope. Such scope correction apparatus receives light from a scene that is located a relatively short distance from the scope such that, without the presence of the scope correction apparatus, the focal point of the light within the scope would not be overlaid with the scope reticle. The scope correction apparatus optically alters the light such that its focal point is overlaid with the scope reticle thereby correcting for optical aberrations caused by the short distance between the scene and the scope. Accordingly, the user is able to view through the scope clear images of both the scene and the reticle.

Abstract: A laser diode collimating and aberration correction (LDCC) molded plastic optical system having a refractive lens(es) to collimate fast axis and a refractive lens(es) to collimate the slow axis of the laser diode (this lens combination is termed a cross cylindrical lens system) with a diffractive element(s) to correct for astigmatism and provide circularization of the output laser beam. All optical elements are molded in plastic to high tolerances with regard to the surface optical figure (shape of the curved surface), surface roughness, and alignment between surfaces (tilt, rotation, and translation). With proper alignment of the optical system to a suitable laser diode emitter, the combination of optic and laser diode is capable of delivering diffraction limited performance—collimated beam, circular beam cross section, and no astigmatism.
