Freeform optics have been the subject of much research in recent years. Advances in theories of aberration control, single-point and patch-contact manufacturing methods, [...]

BENJAMIN VACA. Anti-Reflective Structured Surfaces on Optical Windows Through Tunable Metallic Etch Masking (Under the direction of DR. ISHWAR AGGARWAL and DR. THOMAS HUT[...]

Freeform optics, broadly described as optical elements with at least one surface lacking translational or rotational symmetry, have seen increased interest due to recent [...]

The advent of metamaterials has increased the complexity of possible light-matter interactions, creating gaps in knowledge and violating various commonly used approximati[...]

Scenes containing laser illumination are commonly encountered in a variety of remote-sensing applications. One aspect of laser illumination is that it can interfere with[...]

Binary-phase diffraction gratings are optical components that distribute an incident light beam to diffraction-order directions, due to the periodic modulation of the ref[...]

Although freeform concepts have been considered for many decades, new fabrication capabilities have enabled new classes of optical components and sparked greatly increase[...]

Our ability to harness the power of X-ray radiation has led to many important scientific discoveries. Two common applications for X-rays are crystallography and imaging t[...]

Illumination systems that can create light patterns of varying sizes or shapes with high efficiency and uniformity are advantageous for a range of applications, including[...]

We are developing a real-time infrared imaging technique, Enhanced Thermal Imaging(ETI), that can detect blood vessels embedded in tissue and assess tissue perfusion. ETI[...]
