Abstract: An analyzing system includes a detection area with a transparent window past which an analyte moves and emits or transmits light. One or more polarizing elements receive and polarize the light into respective two or more different polarization components. One or more optical detectors receive the respective two or more polarization components and generate respective at least two signals in response. A processor is coupled to the optical detectors and configured to determine a polarization status of the light from the analyte based on the at least two signals.

Abstract: An analyzing system includes a fluidic stream that guides an analyte in a detection area where the analyte emits or transmits light. One or more polarizing elements polarize the light into respective two or more different polarization components. One or more optical detectors receive the respective two or more polarization components and generate respective at least two signals in response. A processor is coupled to the optical detectors and configured to determine the polarization status of the light from the object based on the signals.

Abstract: An optical device has a first optical layer with a first dispersion response as a first function of wavelength. A second optical layer has a second dispersion response as a function of wavelength that is different than the first function. A separating layer is located between the first and second optical layers and has a lower refractive index than the first layer and the second layer. A thickness of the separating layer is selected such that the first and second dispersion responses combine to create an anomalous dispersion about a target wavelength. The anomalous dispersion results in the optical device emitting a wideband coherent optical output about the target wavelength in response to an optical input at the target wavelength.

Abstract: Embodiments are directed to an apparatus that includes a fluidic structure and optical components. The fluidic structure includes a transparent channel through which objects in an analyte fluid can travel along respective paths during operation of the apparatus. The optical components are configured to provide measurement light to the objects traveling through the transparent channel. The fluidic structure is configured to reversibly engage with a host structure. The host structure includes a source of the measurement light and electronics to receive and process output light emanating from the objects traveling in the channel. The fluidic structure makes an air-tight seal when engaged with the host structure.

Abstract: Approaches for determining the delivery success of a particle, such as a drug particle, are disclosed. A system for monitoring delivery of particles to biological tissue includes a volume, an optical component, a detector, and an analyzer. The volume comprises a space through which a particle can pass in a desired direction. The optical component is configured to provide a measurement light. The detector is positioned to detect light emanating from the particle in response to the measurement light. The detected light is modulated as the particle moves along a detection axis. The detector is configured to generate a time-varying signal in response to the detected light. The analyzer is configured to receive the time-varying signal and determine a delivery success of the particle into a biological tissue based upon characteristics of the time-varying signal.

Abstract: Approaches for determining object position in a flow path are disclosed. A system includes a spatial filter having a length disposed along a longitudinal axis of the flow path and a width along a lateral axis of the flow path. The spatial filter has mask features configured to modulate light. Light emanating from objects moving along the flow path is detected. The detected light has a component along a detection axis that makes a non-zero angle with respect to the longitudinal and lateral axes. An electrical output signal that includes information about the trajectory depth of the object is generated in response to the detected light.
