R.F. transparent RF/UV-IR detector apparatus

A dual-mode, optical and radio frequency detector apparatus comprising:

• a. a primary mirror, said primary mirror comprising an RF-transmissive body having on a front surface thereof an optically reflective, RF-transmissive coating adapted to reflect optical energy forward,
• b. a secondary mirror located in front of said primary mirror, said secondary mirror comprising an RF-transmissive body having on a rear surface thereof an optically reflective, RF-transmissive coating, said secondary mirror being adapted to reflect optical energy rearward, at least one of said optical reflective, RF-transmissive coatings comprising a conductive metal film,
• c. an optical detector rearward of said secondary mirror, said detector being adapted to receive optical energy reflected rearward from said secondary mirror, and
• d. a radio frequency antenna located rearward of said primary mirror, said antenna being adapted to receive radio frequency energy distributed over the entire aperture area of said primary mirror.

A dual-mode, optical and radio frequency detector apparatus comprising:

• a. a primary mirror including a body having a concave front face on which is formed an optically reflective, RF-transmissive surface,
• b. a secondary mirror comprising a body having a convex rear surface on which is formed an optically reflective, RF-transmissive layer, said layer being reflective to optical energy in a first wavelength band and transmissive to optical energy in a second wavelength band of the optical spectrum,
• c. a first optical detector rearward of said secondary mirror, said first detector being adapted to receive optical energy in said first wavelength band reflected from said secondary mirror,
• d. a second optical detector located forward of said secondary mirror, said second optical detector being adapted to receive optical energy in said second wavelength band of said optical spectrum transmitted through said secondary mirror, and
• e. a radio frequency antenna located rearward of said primary mirror, said antenna being adapted to receive radio frequency energy distributed over the entire aperture area of said primary mirror.
