Ray tracing through systems containing holographic optical elements.
While the subject of tracing finite rays through an optical system containing holographic optical elements (HOE's) has been widely discussed in scientific literature, the actual mechanism for determining the direction of a ray leaving a generalized HOE appears not to have been addressed in any great depth. Here a detailed description of a practical method that uses a lookup table approach for tracing finite rays through such systems is presented. Furthermore, the construction geometry is not limited to an arrangement whereby only perfect reference and object beams are used to produce the HOE.
