Simultaneous multiple surface design method for diffractive surfaces

Abstract

The simultaneous multiple surface (SMS) design method is extended to include design of diffractive optical surfaces besides refractive and reflective ones. This method involves the simultaneous and direct (no optimization) calculation of diffractive and refractive/reflective surfaces. Using the phase-shift properties of diffractive elements as an extra degree of freedom, two rays for each point on each diffractive surface are controlled. Representative diffractive systems designed by the SMS method are shown.

Automated design of freeform imaging systems for automotive head-up display applications

“…With the fast development of aberration theory [4,5] and optical manufacturing technologies [6,7], freeform surfaces have been applied in many different areas, such as LED illumination [8,9], head-mounted displays [10,11], hyperspectral systems [12], remote sensing systems [13], and so on. Many scholars have explored various automated design methods for freeform surfaces, such as the Simultaneous Multiple Surface (SMS) method [14,15] and partial differential equations (PDEs) method [16,17]. However, all these methods are only feasible for designing systems with a single or small field of view (FOV), as well as a limited number of freeform surfaces.…”
