Abstract: An apparatus for optical inspection of objects, in particular cans. The apparatus includes an inspection station, a lighting system, and a camera directed towards the inspection system to capture an image of the lateral surface of the object to be inspected. A Fresnel lens is associated with the lighting system to direct a beam of light rays collimated towards the object to be inspected, located in the inspection station. A further Fresnel lens is positioned to face the object to be inspected, located in the inspection station and directed in such a way as to make the collimated light rays converge on the object.

Abstract: An apparatus includes a pipe through which a multiphase fluid flows, with a transparent window structure formed in the pipe. A collimated light source emits light through the transparent window structure into the pipe having a wavelength at which a component of a desired phase of the multiphase fluid is absorptive. A photodetector is positioned such that the emitted light passes through the multiphase fluid in the pipe to impinge upon the photodetector. The photodetector has an actual dynamic range for collimated light detection. Processing circuitry is configured to continuously adjust a power of the collimated light source dependent upon an output level of the photodetector so as to cause measurement of the emitted light over an effective dynamic range greater than the actual dynamic range, and determine a property of the multiphase fluid as a function of the power of the collimated light source.

Abstract: Light is emitted on one side of a paper sheet 100, which is being transported on a transport path, from a first light source 11, and light is emitted on other side of the paper sheet 100 from a second light source 21 and a fourth light source 22. A first light receiving sensor 14 receives a first reflected light, which is the light emitted by the first light source 11 and reflected from the one side of the paper sheet 100. A second light receiving sensor 24 receives a second reflected light, which is the light emitted by the second light source 21 and the fourth light source 22 and reflected from the other side of the paper sheet 100, and receives a transmitted light that is the light emitted by the first light source 11 and that has passed through the paper sheet 100.

Abstract: Conventional optical analysis tools containing an integrated computational element may have an operational profile that is too large for convenient use within confined locales. Optical analysis tools having a miniaturized operational profile can comprise: an electromagnetic radiation source that provides electromagnetic radiation to an optical train; and an optical computing device positioned within the optical train. The optical computing device comprises a planar array detector having at least two optical detection regions. At least one of the at least two optical detection regions has an integrated computational element disposed thereon. The planar array detector and the integrated computational element are in a fixed configuration with respect to one another.

Abstract: A scanner and an attenuated total reflection (ATR) objective for use in such scanners are disclosed. The ATR objective includes first and second optical elements and an input port. The input port receives an input collimated light beam that is focused to a point on a planar face of the first optical element by the second optical element such that substantially all of that portion is reflected by the planar face and no portion of the input beam strikes the planar face at an angle less than the critical angle. The second optical element also generates an output collimated light beam from light reflected from the planar thce that is characterized by a central ray that is coincident with the central ray of the input collimated light beam. A light beam converter receives the first collimated light beam and generates the input collimated light beam therefrom.

Abstract: A spatial filter is made by forming a structure comprising a focusing element and an opaque surface, the opaque surface being disposed remotely from the focusing element in substantially the same plane as a focal plane of the focusing element; and by forming a pinhole in the opaque surface at or adjacent to a focal point of the focusing element by transmitting a substantially collimated laser beam through the focusing element so that a point optimally corresponding to the focal point is identified on the opaque surface and imperfection of the focusing element, if any, is reflected on the shape and position of the pinhole so formed.

Abstract: Apparatus, systems and methods for use in analyzing discrete reactions are provided. The analytical devices of the invention use an array of nanoscale regions (a chip) that has discrete patches, for example, patches of nanoscale regions. In some embodiments an analytical system is provided that has an analysis chip with an array of patches, each of the patches comprising nanoscale regions that emit fluorescent light when illuminated. The system has a two-dimensional (x, y) array of dichroic prisms, each prism comprising a dichroic element that diverts illumination light up in the z dimension of the array to a patch on the analysis chip above it. Each dichroic element transmits fluorescent light emitted by the patch that it illuminates, whereby the emitted light from each patch passes down through each dichroic prism. The analytical system also has a detector below the array of dichroic prisms that detects the transmitted fluorescent light. Such systems are useful for monitoring many analytical reactions at one time including single molecule sequencing reactions.
