Overhang enclosure of a panoramic optical device to eliminate double reflection

A panoramic camera optical component comprising:

• a mirror positioned within an overhang enclosure of the component in a plane approximately parallel to a circular cross section of a quadric reflector, said mirror reflecting environmental light that is reflected into the mirror by the quadric reflector and then into an aperture of the quadric reflector;
• the overhang enclosure having an outer surface that comprises a light absorbing material which absorbs secondary reflections, wherein secondary reflections are light reflected from an interior surface of a transparent outer casing that is not incident on the quadric reflector, wherein the outer surface of the overhang enclosure absorbs a significant portion of the light reflecting off an interior of the transparent outer casing the secondary reflections;
• and
• wherein the transparent outer casing is cylindrical around the quadric reflector and overhang enclosure, wherein a topmost portion of the overhang enclosure is secured to a topmost portion of the transparent outer casing, wherein a bottommost portion of the transparent outer casing is securable to a structure that supports the quadric reflector, wherein an interior volume of the transparent outer casing when secured to the structure includes the quadric reflector, the mirror, and the overhang enclosure, wherein a shape of the overhang enclosure permits environmental light to reflect off the quadric reflector without operational blockage.

A device comprising:

• a base comprising of a housing, wherein the housing comprises of:
• a quadric reflector having an approximately conical shape, which tapers from a wide base to an apex, said apex comprising an aperture;
• and
• a set of one or more optical elements positioned at least partially within a volumetric region of the quadric reflector, said one or more optical elements focusing light passing through the aperture;
• a screwable top secured comprising:
• a mirror positioned within an overhang enclosure of the device in a plane approximately parallel to a circular cross section of a quadric reflector when the screwable top is secured to the base, said mirror reflecting environmental light that is reflected by the quadric reflector into an aperture of the quadric reflector;
• the overhang enclosure having an outer surface that comprises a light absorbing material which absorbs secondary reflections, wherein secondary reflections are light reflected from an interior surface of a transparent outer casing that is not incident on the quadric reflector, wherein the outer surface of the overhang enclosure absorbs light reflecting off an interior of the transparent outer casing the secondary reflections, and wherein an inner wall of the overhang enclosure absorbs light refracted by the transparent outer casing which travels tangentially across a surface of the quadric reflector;
• and
• wherein the transparent outer casing is cylindrical around the quadric reflector and overhang enclosure, wherein a topmost portion of the overhang enclosure is secured to a topmost portion of the transparent outer casing, wherein a bottommost portion of the transparent outer casing is securable to a structure that supports the quadric reflector, wherein an interior volume of the transparent outer casing when secured to the structure includes the quadric reflector, the mirror, and the overhang enclosure, wherein a shape of the overhang enclosure permits environmental light to reflect off the quadric reflector without operational blockage.
