  • Patent number: 6196690
    Abstract: Radiant energy sensor is protected from severe environments with a radiant energy sensor assembly that off-sets the sensor from the environment. The sensor assembly includes a radiant energy sensor, a pair of reflective walls facing one another, one of the walls having a transmissive aperture for receiving radiant energy over a wide angle of incidence, an entry, the other wall having a transmissive aperture for passing energy from behind the wall to the sensor, an exit, with the walls having the reflection characteristics such that the radiant energy entering the entry aperture at any angle is always reflected to the exit aperture. The reflective walls may be paraboloids or Fresnel surfaces in geometry.
    Type: Grant
