Modular projector cage and stacked frame using same

A modular projector cage for supporting an optical projector, comprising:

• a rectangular hexahedral open frame formed by tubes connected by corner fittings and having parallel top and bottom sections;
• a projector mounting plate configured to support the optical projector and having opposite sides and opposite front and rear ends;
• first and second articulated elevation assemblies respectively mechanically connected to the first and second sides of the mounting plate adjacent the front end by respective first and second articulated mechanical connections each capable of articulated movement, and mechanically connected to the bottom section, the first and second articulated elevation assemblies being independently adjustable by respective first and second threaded rods to adjust an amount of pitch and an amount of roll of the mounting plate;
• a yaw assembly operably connected to the rear end of the mounting plate via a mounting fixture having a threaded portion that engages a third threaded rod such that rotation of the third threaded rod generates an amount of a yaw of the mounting plate;
• and
• wherein generating the amount of yaw causes the articulated movement of the first and second articulated mechanical connections of the first and second articulated elevation assemblies.

A method of adjusting pitch, roll and yaw of an optical projector housed in a modular projector cage, comprising:

• mounting the optical projector onto a mounting plate on a bottom section of the modular projector cage;
• adjusting the pitch and roll using first and second articulated elevation assemblies operably connected to the mounting plate adjacent a front end of the mounting plate via respective support arms and support brackets;
• and
• adjusting the yaw using a yaw assembly operably connected to the mounting plate adjacent a rear end of the mounting plate, wherein adjusting the yaw causes articulated movement of the support arms and support brackets of the first and second articulated elevation assemblies.

A method of adjusting pitch, roll and yaw of an optical projector housed in a modular projector cage, comprising:

• mounting the optical projector onto a mounting plate having front and rear ends, wherein the mounting plate is movably connected to a bottom section of the modular projector cage adjacent the front end by articulated mechanical connections each capable of articulated movement and adjacent the rear end by a rotatable mechanical connection capable of rotational movement;
• adjusting the pitch and roll adjacent the front end of the mount plate;
• adjusting the yaw adjacent the rear end of the mounting plate;
• and
• wherein adjusting the yaw causes rotation of the rotatable mechanical connection and causes articulated movement of the articulated mechanical connections.
