A concise, tutorial guide to measuring optical radiation, designed for self-instruction and practical reference.
This edition presents the essential radiometric quantities and their interrelationships, including radiant energy, radiant exposure, radiant fluence, radiant density, radiant intensity, and spectral quantities. It connects these concepts to earlier material and sets up the measurement equation through clear examples and explanations. A focus on how time, distance, and geometry affect measurements helps readers understand both theory and practice in radiometry and photometry.
- Define and relate key radiometric quantities used in optical radiation measurements.
- Explore how time variation and geometry influence irradiance and related values.
- Understand the inverse-square law and practical approximations for real sources and receivers.
- Work through illustrative problems that introduce the measurement equation and solving steps.
Ideal for readers who want a solid, approachable foundation in radiometry with ready-to-use concepts and methods.
