Lighting and Radiation Measurements - Fundamentals and sensors

5 important questions on Lighting and Radiation Measurements - Fundamentals and sensors

For what measurements must the spectral sensitivity match the sensitivity of the human eye?

Photometric measurements

What are the two main approaches to the correct weighting of incident radiation?

  1. The sensor already has the required sensitivity
  2. Spectral measurements will be taking and then weighted with applicable sensitivity curve

What four aspects are of importance for photometric sensors?

  1. (absolute) sensitivity
  2. relative spectral sensitivity
  3. size of the photosensitive area A
  4. Dark Current I0
