The article focuses on enhancement of advanced freeform optics by using subaperture stitching. Topics include advancement in freeform fabrication technology with improved diamond turning, grinding, and polishing machines; information on profilometry which is a cost-effective technique for measuring aspheric shapes; and an information that subaperture stitching lacks the ghosting and other diffraction artifacts in a computer-generated hologram that can corrupt mid-spatial frequency estimates.
This article reports that rapid prototyping has evolved from a relatively simple modeling technique that allows design engineers to "test" their ideas in three dimensions to a sophisticated custom-manufacturing tool that may one day find its place alongside the copy machines at the local copy center or in the parts department at the local automobile dealership. Direct metal deposition is a laser-melting process that uses a powder nozzle to deposit metal powder onto existing tools to build the components layer by layer. While the last few years have seen the development of new rapid-prototyping technologies and processes that overcome the geometry problem, the available materials have not had adequate properties to enable them to build production-quality parts. INSET: High-power lasers enable metal-powder prototyping.
