title: Ray-matrix approach for diffractive optics.
abstract: Ray matrices are a powerful tool for the analysis of optical systems. This technique is modified to include a diffractive optical element within the optical system. Several research applications are discussed, including optical Fourier transforms and imaging with diffractive optical elements.
