Abstract: A line illuminating apparatus comprises a pair of irradiating units 12a, 12b of the same structure. The irradiating unit 12a. The light irradiating unit 12a includes a light source 14a, a first light guide 16a consisting of a large number of optical fibers, a light connector 18a, and three second light guides 20 (20a to 20c). The first light guide 16a permits the light emitted from the light source 14a to be incident as a slender rectangular light ray on the light connector 18a. The light emitted from the light connector 18a is divided by the three second light guides 20. Each light guide 20 is in the form of a thin plate, and the light emitting surfaces of the light guides 20a to 20f are arranged to define a imaginary semicylindrical plane surrounding the irradiating line L of work 28. The particular construction is effective for suppressing the loss of energy required for illumination. Also, the inspection is not adversely affected by the presence of, for example, an irregularity on the surface of the work.

Abstract: A hand-held, battery operated, single photon sensitivity phytoluminometer is claimed for rapid, simple nondestructive, noninvasive evaluation of photosynthetic topography in green leaves. All the steps for generating phytoluminescence are performed within a single, light tight enclosure. The sensitivity of the instrument is such that stress induced changes in photosynthesis can be detected seconds after occurrence. Thus phytoluminography is made an easily applied technique for practical use by all those concerned with plant life.

Abstract: The invention is an automated solder joint inspection system for determining the quality of a specular soldered joint through examination of the shape of the joint surface using a series of point light sources and the associated highlight reflections from the joint surface. The light from point light sources, which is directed toward the solder joint, is reflected in a pattern from the solder joint to an array of light responsive transducers from at least one location. Utilizing the intensity values from the light responsive transducer array, the surface orientation of the solder joint at a number of points is determined. The solder joint is evaluated in one of two ways. In one way, using known surface features of solder joints along with curve fitting techniques, a series of grid maps is mathematically interpreted to reconstruct the solder joint surface. A rule-based system, through comparison with acceptable solder joint surface features, evaluates and classifies the joint for an acceptability determination. In another way the surface orientation is used to generate an Extended Gaussian Image of the joint and the features of this are analyzed.

Abstract: An apparatus and method continuously samples and measures the changing concentration and/or density of suspended solids in a liquid medium without electrical connections at the submerged points in the liquid. A submersible sensing head is connected by an elongate probe to an non-submersible enclosure which contains at least one light source and one light detector. The sensing head has an apertured sample chamber allowing liquid to flow freely therethrough when submerged and contains at least one light emitting lens and at least one light receiving lens aligned in the flow path. The light emitting lens is connected to the light source and the light receiving lens is connected to the light detector with fiber optic bundles extending the probe. An elongate shaft extends through the probe and into the sensing head sample chamber and has a lens wiper at its lower end. The shaft is reciprocated by a timed motor in the enclosure to move the lens wiper between the lenses to wipe them clean of debris at selective continuous or intermittent cycles. When the sensing head is submerged light is transmitted from the light source to the emitting lens through the liquid between the lenses to the receiving lens and to the light detector for determining the concentration and/or density of suspended solids in the sample liquid with no submerged electrical connections.

Abstract: A vertical beam spectrophotometer for measuring the light absorption of an assay prepared using standard wet chemistry procedures and conventional solid phase coated bead technology is disclosed. The spectrophotometer measures the absorption of the assay in a conventional reaction cuvette with the bead remaining in the cuvette. The light source of the spectrophotometer illuminates the bead, which diffuses the light into the surrounding assay solution. A lense projects the diffused light onto a photocell which converts it into an electrical signal having magnitude related to the light absorption of the assay. The signal is processed in a known manner by conventional processing circuitry to obtain an absorption value.
