  • Patent number: 11047790
    Abstract: 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.

  • Patent number: 10175476
    Abstract: 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.

  • Patent number: 10151680
    Abstract: 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.

  • Patent number: 7110118
    Abstract: A method and apparatus for performing optical microscopy in one to three dimensions employs a spectral self-interference fluorescent microscopy technique that includes providing at least one fluorescent microscopy sample, at least one objective lens, and at least one reflecting surface. The fluorescent sample is disposed between the objective lens and the reflecting surface, the distance from the sample to the reflecting surface being several to several tens times an excitation wavelength. Excitation light causes the fluorescent sample to emit light, at least a portion of which is reflected by the reflecting surface. The objective lens collects the reflected light and the light emitted directly by the fluorescent sample. The direct and reflected light interfere causing spectral oscillations in the emission spectrum. The periodicity and the peak wavelengths of the emission spectrum are spectroscopically analyzed to determine the optical path length between the fluorescent sample and the reflecting surface.

  • Publication number: 20060182659
    Abstract: An assay system having a channel bounded by first and second reflective surfaces adapted to accommodate a fluid material therebetween and defining a plurality of regions in an array between those surfaces with each region defining a resonant cavity and adapted to receive a capturing material on a surface thereof whereby a source of radiation illuminates each region to provide a standing wave of radiation of within the cavity indicative of binding of said capturing agent to material under investigation, a binding thereof being detected in response to radiation from each cavity indicative of a change in the standing wave pattern.

  • Publication number: 20040036884
    Abstract: A method and apparatus for performing optical microscopy in one to three dimensions employs a spectral self-interference fluorescent microscopy technique that includes providing at least one fluorescent microscopy sample (220a, 220b), at least one objective lens (201), and a reflecting surface (204). The fluorescent sample is disposed between the objective lens and the reflecting surface, the distance (d1, d2) from the sample to the reflecting surface is several to several tens times an excitation wavelength. Excitation light (216) causes the fluorescent sample to emit light (214), at least a portion (214b) of which is reflected by the reflecting surface. The objective lens collects both the reflected light and the light emitted directly by the fluorescent sample (214a). The direct and reflected light interferences causing spectral oscillations in the emission spectrum.
