ABSTRACT:
Disclosed is a reticle generator having an azimuth array (64) of light emitting diode filament lines and an elevation array (66) of orthogonal light emitting diode filament lines. The arrays (64, 66) are fixed by rigid bracket members (136, 144) with respect to the faces (74, 80) of a partially reflecting prism (76). An illuminated LED filament line projected into the prism (76) by azimuth array (64) is reflected by the partially reflecting surface (82), and emitted from prism face (84). A selected LED filament (78) from elevation array (66) is transmitted through the prism (76) and emitted from face (84) and thus superimposed with the azimuth filament line (72).
