Alexander teaches multi broadband laser of claim 9, further comprising a housing encloses a volume containing the at least a first dichroic mirror, the first and second visible or EO light sources, the first imaging dichroic mirror, and the infrared light source (laser module 111 that includes a red laser diode, labelled “R” in FIG. 1, a green laser diode, labelled “G” in FIG. 1, [0054]; the laser module including an infrared laser diode to output an infrared light and at least one visible light laser diode to output a visible light, [0012]).
It would have been obvious to one of ordinary skill in the art at the time the application was filed to modify the multi broadband laser to include a housing encloses a volume containing the at least a first dichroic mirror, the first and second visible or EO light sources, the first imaging dichroic mirror, and the infrared light source, as taught by Alexander for the predictable advantage of securing the LEDs and the mirrors and capable of providing high-quality images to the user without limiting the user's ability to see their external environment, as taught by Alexander in [0004-0006] and Fig. 1).
Claim 18 is rejected under 35 U.S.C. 103 as being unpatentable over Chen et al. (US 20090153977) in view of Swan et al. (US 2011/0249432), and further in view of Chen et al. (US 2005/0275925, hereinafter Chen’925).
Regarding claim 18, the modified Chen teaches the multi broadband laser according to claim 17 (see above). Modified Chen doesn’t explicitly teach, wherein the housing is further configured to include a desiccant within the volume.
Chen and Chen’925 are related as light modules.
Chen’925 teaches the housing is further configured to include a desiccant within the volume (the package, or light modulator 200, also includes a desiccant 260 positioned within the volume sealed by the casing 230, [0018]).
It would have been obvious to one of ordinary skill in the art at the time the application was filed to modify the multi broadband laser of modified Chen to include a desiccant within the volume, as taught by Chen’925, for the predictable advantage of absorbing and trapping moisture to maintain a dry environment
