Design and fabrication of a freeform

WebJan 14, 2012 · This paper focuses on the design, fabrication, and metrology technologies of the ultra-precision optical freeform surface for progressive addition lens (PAL). The PAL, which has a front surface with far-view zone, near-view zone, and intermediate zone, was used to remedy presbyopia by distributing optical powers of the three zones. WebIt has been a challenge to design an optical see-through head-mounted display that is compact, lightweight, and stray-light-suppressed by using freeform optics. A new type of design based on freeform prisms is presented. The system consists of three optical elements and a micro-display. Two prisms serve as near-eye viewing optics that magnify …
