3. Optical measurements
3.1 Transmitter power
For most applications, such as the optimum injection of light into an optical fiber, three parameters are important: the power (or energy flux) emitted, the dimensions of the light spot on the emitting face (also known as the "near field") and the angular emission pattern (also known as the "far field").
The "far field" is the Fourier transform of the "near field".
