Incoherent Addition to Generalize Depolarization in Light Scattering Models
Models for polarized light scattering are relevant for creating virtual reality scenes. To get a “real” looking model, the light scattering on the model needs to be simulated correctly to get a realistic model. The polarimetry of objects is measured in the lab, fit to a model, and this model is used to simulate the polarized light scattering...

Reflective Objective Microscope
The invention is an all-reflective microscope with the unique characteristic that has an off-axis configuration with freeform surfaces. This configuration was not possible in the past due to the limitations in the design, fabrication, and testing of freeform optics. By integrating freeform optics in an off-axis setup, this design increases the efficiency...

Optical System for Spectral Imaging
This technology is an optical system with freeform elements that disperses and images the light from an object to a digital sensor for spectral imaging. Compared to traditional systems, which use rotationally symmetric optical systems with a separate dispersion element, the current invention is much more compact and low-cost. The optical system with...
