A beam splitter divides incident light into reflected and transmitted beams at a specified R/T ratio. For a lossless beam splitter, R + T = 1. One of the biggest challenges for modeling such a system is that multiple ray paths cannot be simultaneously traced in Sequential Mode. Thus, multiple configurations are needed to trace rays along both the transmitted and. Three techniques to model diffractive beam splitters – two in Sequential and one in Non-Sequential modes: 2. Method A: Diffraction Grating surface and multi-configuration 2. Development steps Inserting general parameters for simulation (wavelength, aperture,. Field 1 evolves as E1 ! T E3 + RE4, where T; R are the transmission and re ection coe cients for the beam splitter. The transformation matrix is then given by. Separate (focused) beams or light points are of interest for a wide range of applications, whether for manufacturing processes, for special fiber coupling, for face recognition systems or light marker generation.
