Extended Depth of Focus Contact Lens Design
Presbyopia is an ophthalmic condition where the eye loses the ability to focus clearly due to lens aging. It can significantly affect the quality of life. Since eventually every person is undergoing this condition, it’s important to find a solution to it. Spectacle-free treatment can be achieved by contact lenses and intraocular lenses. A lens...

Contact Lenses to Control Myopia Progression
The population of myopia patients has been booming worldwide. Although myopia can be easily corrected with optical and surgical interventions, pathological myopia is known to increase the risk of eye diseases such as cataracts, glaucoma and macular degeneration which cause large social economic burden worldwide. The genesis of myopia remains uncertain,...

Rapid Assessment and Visual Reporting of Local Particle Velocity
This invention provides rapid determination of regional blood flow within a vessel over time. Building on our advances in adaptive optics ophthalmoscopy, we combine fast camera capture with high spatial resolution to resolve single blood cells moving within vessels of the eye. The invention provides a computational strategy to processes data in real-time...

Enhanced Contrast Imaging Using DMD Array as Confocal Filter
Traditionally, confocal imaging strategies use a small pinhole aperture at the imaging plane to reject scattered light and light that is out of focus from the optical plane of best focus. We describe a new imaging detection scheme that incorporates a digital micromirror device (DMD) at the imaging plane to provide a fast a dynamic “synthetic aperture”...

Camera-Based Testing of Photonic Integrated Circuits
The invention is in the area of non-contact testing of photonic integrated circuits. The state of the art in photonic circuit testing requires either cumbersome probes or requires fibers to be aligned to coupling locations at the edge of the die. It has been well known for some time that a sensitive microscope camera combination can detect even weakly...

Stepped Light Guides
Brief Description:The intection prisms of a right angle light guide are positioned in a stepped two-dimensional array, such that they will not obstruct or divert any light already traveling down the light guide.Applications:For a high efficiency wave guide for either collecting light incident on one face and transmitting it to one edge, or alternatively...
