LAC Test Results / Actions

• Optical Calibration

  • Radiometric
    • Initial Results Consistent with Models
    • Offset Error Limits Dynamic range to 11 bits. Difficult to Differentiate High Albedo from Specular Reflection. 60 Hz Operation Provides Viable Fix.
    • Unexpected Temperature Dependence of Quantum Efficiency
  • Spectral
    • Filters Have Excellent Spectral Characteristics
    • Analysis Continues
  • Alignment: Within 2 arc-min of ALI Track-- achieved 1
  • Flat Field: Solar Calibrators Consistent with Diffuse Illumination
