Abstract

Diffractive optics represents a new and fundamental optical manufacturing technology that has tremendous potential in both the government and commercial sectors. Diffractive optics technology provides system designers with new and exciting degrees of freedom for the design and optimization of precision optical systems. Using diffractive optics one can: provide color correction for projection systems using a single, economical refractive material; create aspheric wavefronts without using aspheric surfaces; eliminate the need for exotic (and expensive) flint-type materials; produce high-performance, high-numerical-aperture, lightweight optical elements; produce high performance microlens arrays; construct custom diffusers for beam homogenization and beam shaping; convert Gaussian beams to a square- aperture, flat-top beam profile, create novel polarization components and narrowband filters; athermalize optical systems; and reduce the weight, complexity and cost of optical systems--all of which are important for projection display systems. In this paper, we describe several features of diffractive optical elements that are useful for projection display applications.
