Abstract: A method is disclosed for selecting an optimal value for an adjustable parameter of a structured light metrology (SLM) system, for scanning an object. The SLM system performs test scans of the object to acquire a plurality of sets of measurements of the object, wherein a different value is used for the parameter for each test scan. For each test scan, a value of a quality metric is calculated, based on the set of measurements of the object associated with the test scan and simulation data representing a simulated scan of the object by the SLM system. A test scan is then identified that has a quality metric value that satisfies a specified optimization criterion; and a value of the adjustable parameter that was used for the identified test scan is selected as the optimal value of the adjustable parameter, for scanning the object.

Abstract: Embodiments of the invention provide an imaging system and method using adaptive optics and optimization algorithms for imaging through highly scattering media in oil reservoir applications and lab-based petroleum research. Two-/multi-photon fluorescence microscopy is used in conjunction with adaptive optics for enhanced imaging and detection capabilities in scattering reservoir media. Advanced fluorescence techniques are used to allow for super-penetration imaging to compensate for aberrations both in and out of the field of interest, extending the depth at which pore geometry can be imaged within a rock matrix beyond the current capability of confocal microscopy. The placement of a Deformable Mirror or Spatial Light Modulator for this application, in which scattering and index mismatch are dominant aberrations, is in an optical plane that is conjugate to the pupil plane of the objective lens in the imaging system.

Abstract: A method for measuring the activity of one or more excitable cells, such as neurons, in a target tissue is provided. The present method may include measuring the activity of individual, selected excitable cells by projecting one or more three dimensional (3D) multi-focal laser light patterns into a target tissue containing excitable cells adapted to emit cellular electrical activity—sensitive fluorescence, to generate a multiplexed 2D diffraction pattern of fluorescence emitted by the neurons, and resolving the multiplexed 2D diffraction pattern. Also provided herein is a system configured to perform the present method, the system including a microscope configured to project one or more 3D multi-focal laser light patterns into a target tissue using a spatial light modulator and a mirror galvanometer, and a microlens array and an image detector to record individual and multiplexed 2D diffraction patterns of light emitted from the target tissue.

Abstract: In an illumination system (12, 13) for a scatterometer, first and second spatial light modulators lie in a common plane and are formed by different portions of a single liquid crystal cell (260). Pre-polarizers (250) apply polarization to first and second radiation prior to the spatial light modulators. A first spatial light modulator (236-S) varies a polarization state of the first radiation in accordance with a first programmable pattern. Second spatial light modulator (236-P) varies a polarization state of the second radiation accordance with a second programmable pattern. A polarizing beam splitter (234) selectively transmits each of the spatially modulated first and second radiation to a common output path, depending on the polarization state of the radiation. In an embodiment, functions of pre-polarizers are performed by the polarizing beam splitter.

Abstract: An optical detector comprises a plurality of pixels, each pixel comprising a photodiode operable to detect light incident on that pixel and to generate a signal indicative of an intensity of that light. The plurality of pixels comprises a plurality of pixel pairs, and for each pixel pair, in a configuration mode, the detector is arranged to compare the signal generated by a first pixel of the pair with the signal generated by a second pixel of the pair. A method of optical detection is also described, as is a system incorporating the described optical detector.

Abstract: Methods are provided to identify spatially and spectrally multiplexed probes in a biological environment. Such probes are identified by the ordering and color of fluorophores of the probes. The devices and methods provided facilitate determination of the locations and colors of such fluorophores, such that a probe can be identified. In some embodiments, probes are identified by applying light from a target environment to a spatial light modulator that can be used to control the direction and magnitude of chromatic dispersion of the detected light; multiple images of the target, corresponding to multiple different spatial light modulator settings, can be deconvolved and used to determine the colors and locations of fluorophores. In some embodiments, light from a region of the target can be simultaneously imaged spatially and spectrally. Correlations between the spatial and spectral images over time can be used to determine the color of fluorophores in the target.
