Abstract:
A machine for inspecting glass containers rotating at an inspection station. A camera images an area of interest on the glass container and continuous illumination of that area is provided by strobing a light source a number of times while the area is imaged on a camera the entire period.

Abstract:
An apparatus and method are provided for creating an image of a microarray. The apparatus includes at least one light source configured to direct light toward the microarray. The apparatus includes an excitation filter configured to filter the light into a first frequency band towards dichromatic mirror. The dichromatic mirror reflects light onto the microarray causing the microarray to emit electromagnetic energy. The apparatus includes emission filter configured to filter the electromagnetic energy within a second frequency band. The apparatus further includes an imaging unit having a charged coupled device (CCD), the CCD having an imaging surface masked by a pinhole blind such that when the pinhole blind receives electromagnetic energy from the emission filter, an image is created of the entire micro array.
Abstract:
A machine for inspecting a container which is being conveyed along a linear path. The machine has spaced left hand and right hand cabinets in front of the linear path with the space therebetween being space in which an operator can stand to be proximate to the linear path. The machine has left hand and right hand inspection stations which include a left-hand assembly located in front of the linear path and a right hand assembly located in front of the linear path. These assemblies are pivotally mounted about vertical axes so that they can be pivoted from a closed position proximate the liner path to a retracted position away from the linear path. At the retracted position an operator can enter the machine and service the inspection stations.
Abstract:
A machine for inspecting a container which is being conveyed along a linear path. The machine has cabinets situated in front of the conveyor path at either side of a central open area in front of the conveyor path which is to be used by an operator for servicing the conveyor. The interior sides of these cabinets are open for access to electronics and the central opening is closed by a pair of doors which are releasably attached to the sides of the cabinets and can be push in to provide access to the central area and can be pulled from the cabinets to provide access to electronics through the open sides of the cabinets.
Abstract:
In a machine-vision system for inspecting a part or either object, the invention provides a method and apparatus providing illumination with high-speed changing and/or automatic adjustment of not only the illumination's angle, but also the dispersion, intensity, and/or color. Optionally, a light source emits polarized light, a machine-vision imager obtains an image, and a processor receives the image and generates a quality parameter based on the image. One or more of the various means described selectively direct the light in a predetermined pattern based on its polarization and based on the quality parameter of the image. A machine-vision method includes setting one or more illumination parameters, illuminating the object based on the one or more illumination parameters, obtaining an image of the illuminated object, generating a quality parameter based on an image quality of a predetermined region of interest in the image, and iterating using a different illumination parameter.
Abstract:
Systems, devices and methods are provided for viewing a pattern of biological material stained with dyes capable of absorbing, scattering or fluorescing light when illuminated by light emitting diodes (LEDs). The system includes a light source containing multiple light source arrays of different LED types emitting light at different wavelengths optimized for detecting specific dyes, a diffuser, a detector or viewer, and optional optical filters to ensure that the only light reaching the detector or viewer is light produced by fluorescence of the various dyes within a specific wavelength band. The optical filters are optional for detecting or viewing absorbance and light scatter. The different arrays of LED types can be selected in any combination during illumination and their intensity is adjustable over a range from 0-100%. A system and method is also provided for comparing patterns for two or more dyes contained in a single material.
Abstract:
An illumination head (1) for machine vision has an annular support (2) with first, second, third, and fourth illumination sections (3, 4, 5, and 6). The third section (5) has three sets of LEDs (12, 13, 14) arranged in a pattern so that each set illuminates at approximately the same angle. Each set is driven in succession so that a series of three monochrome images at the same angle are captured. These are superimposed by an image processor to provide a color image, although the camera is monochrome. More information can be obtained in such a color image and the high resolution and robustness of monochrome cameras is availed of.

The present invention discloses a monolithic integration device and micro Total Analysis System. The monolithic integration device for sensing comprises: a micro-LED; an optical detector; and a sensing channel, wherein the micro-LED is coupled with the sensing channel and is configured for emitting light into the sensing channel, and the optical detector is coupled with the sensing channel and is configured for sensing the light which is emitted by the micro-LED and travels through at least one part of the sensing channel. An embodiment of this invention proposes a new monolithic integration device for sensing with built-in light source and optical detection system.
