Title: FEMTOPROJECTOR OPTICAL SYSTEMS
Abstract:
A variety of femtoprojector optical systems are described. Each of them can be made small enough to fit in a contact lens using plastic injection molding, diamond turning, photolithography and etching, or other techniques. Most, but not all, of the systems include a solid cylindrical transparent substrate with a curved primary mirror formed on one end and a secondary mirror formed on the other end. Any of the designs may use light blocking, light- redirecting, absorbing coatings or other types of baffle structures as needed to reduce stray light.
