Telethrone : a situated display using retro-reflection basedmulti-view toward remote collaboration in small dynamic groups
… version of the new technology approach combined retro-reflective material with aligned pairs of cameras, and projectors, connected by IP video. A counterbalanced repeated measures experiment to analyse gaze interactions was undertaken. Results suggest that the remote user is not excluded from …

Transillumination techniques in ophthalmic imaging
… cornea and retina is typically performed in a reflection geometry. Images are formed from light that has backscattered off corneal microstructures or backreflected from the retina. In this configuration, artifacts caused by superficial surface reflections are often encountered. These unwanted …

Theory and Experiments of Scattering From Microscale Random Rough and Deterministic Surfaces
… angles and surface geometric parameters on the reflection distribution. A geometric optics approximation to the rigorous electromagnetic theory is developed for random rough surfaces. The approximate results agree well with the FTIR experimental findings, indicating that the geometric optics …

Integrated Wavelength Stabilization Of Broad Area Semiconductor Lasers Using A Dual Grating Reflector
… grating will operate under total internal reflection conditions allowing a near unity retro-reflection of the light of the stabilization wavelength. The grating coupler and feedback grating together comprise a dual grating reflector (DGR). The DGR wavelength stabilization scheme is …
