Claim of US Patent No. 10,234,105

1. An imaging automated luminaire comprising:an elliptical reflector having a first focal point internal to the elliptical reflector and a second focal point external to the elliptical reflector;
a light source located at the first focal point, the light source and the elliptical reflector configured to generate a light beam having an optical axis;
an imaging gate positioned at the second focal point;
an imager mounted adjacent to the imaging gate, the imager configured to convert the light beam into an imaged light beam directed to a Fresnel output lens without passing through intervening lenses; and
a pan and tilt movement gimbaled housing for the elliptical reflector, light source, imaging gate, imager and Fresnel output lens,
wherein the Fresnel output lens comprises a polymer lens, and
wherein the Fresnel output lens is articulable along the optical axis to adjust a focus of the imaged light beam.
