Linearity

Image quality and reliability requires linearity of the source camera. As spectral radiance (light level) changes, so should the brightness of observations from a sensor. Otherwise, pixel digital numbers (DN) cannot be equated to radiance, i.e. camera intensity levels will not effectively indicate the light level present. I2R can verify the linearity of a camera system by imaging an integrating sphere with a systematically varying light level. I2R has integrating spheres with NIST-traceable spectrometers used to monitor radiance levels. By relating acquired images to measured radiance, the linearity of a camera system can be verified.



I2R Provides:
  • Individual camera linearity measurements using integrating spheres with radii ranging from 5cm to 1 m.
  • Linearity analysis for each camera spectral band
