Optical Design & Engineering

Fourier incoherent single-channel holography can record spatially incoherent digital holograms, avoiding the twin-image problem. This could enable the development of instruments such as holographic telescopes and video cameras.

Novel polishing techniques on pre-cut segments may speed the manufacture of aspheric mirrors for large telescopes.

Technology modeled on car headlamps provides the basis for efficient collection of sunlight.

A new projection method using laser diodes, optical fibers, and liquid crystal phase modulators can produce color, high-quality, high-contrast images with a handheld device and without photon loss.

Light irradiation of a metallic nanostructure enables a novel thermoplasmonic optical tweezer for nanoparticles.
