An enhanced single particle interferometric reflectance imaging system includes an illumination source configured to produce illumination light along an illumination path toward a target substrate. The target substrate can be configured to reflect the illuminating light along one or more collection paths toward one or more imaging sensors. The target substrate includes a base substrate having a first reflecting surface and a transparent spacer layer having a first surface in contact with the first reflecting surface and a second reflecting surface on a side opposite to the first surface. The transparent spacer layer has a predefined thickness that is determined as a function of a wavelength of the illuminating light and produces a predefined radiation pattern of optical scattering when nanoparticles are positioned on or near the second reflective surface. In addition, one or more of the collection paths can also include an amplitude mask selected to match the radiation pattern.

A system and method for correction of aberrations in a solid immersion microscopy system using a deformable mirror. A solid immersion lens is provided having a surface configured to make optical contact with a nearly planar surface of a substrate, an object to be imaged disposed on the opposite side of the substrate. A convex surface of the solid immersion lens faces an objective lens. A deformable mirror assembly, including a plurality of individually controllable actuators, receives light transmitted from the object. A control system controls in communication with the deformable mirror assembly provides individual actuation of each of the actuators of the deformable mirror to compensate or counteract the effects of aberrations.

Systems and methods for high-throughput processing of assay plates include a calibration nanoparticle to facilitate automated focusing of the imaging system. An assay plate includes a base layer, a transparent layer in contact with the base layer, and at least one calibration nanoparticle having a pre-defined size immobilized on the assay plate surface. The assay plate surface can be functionalized to selectively bind to biological targets. The assay plate can be used in an imaging system for high-throughput autofocus and biological target detection.

A dual-phase interferometric method and device for charge modulation mapping in integrated circuits provides significant improvement in signal to noise ratio over conventional detection configurations. The method and device can be used for failure analysis and testing of advanced technology IC chips for which high sensitivity in modulation mapping is required.

Stimulation of the central nervous system can be useful for treating neurological disorders. Wireless neurostimulating devices have the benefit that they can float in tissue and do not experience the sheering caused by tethering tension that connecting wires impose on the stimulators. An optically powered, logic controlled, CMOS microdevice that can decode telemetry data from an optical packet is a way of implementing wireless, addressable, microstimulators. Through the use of an optical packet, different devices can be addressed for stimulation, allowing spatially selective activation of neural tissue. The present invention, involves such a neural stimulation device, specifically an optically powered CMOS circuit that decodes telemetry data and determines whether it has been addressed.
