Abstract: Reflectance apparatus is disclosed for obtaining measurement of nonspecular reflected light in which controlled light rays are directed along a transmission path from a light source through a plurality of light traps to expose or illuminate a specimen and nonspecular reflected light is passed from the specimen through the light traps along a transmission path to one or more detectors where the nonspecular reflected light is measured, the detector's field of view being larger than the illuminated area of the specimen over a wide range of specimen to source and detector distances.

Abstract: A portable hand held instrument is capable of making accurate colorimetric measurements in the field. The instrument has a body which houses the electronic circuitry and a door which allows a vial having a solution to be measured to be placed therein. The vial is illuminated lengthwise by a light beam of two wavelengths, one of which serves as a reference. The light emerging from the top of the vial is spatially integrated and directed to a detector. The detector measures the intensity of the transmitted light, and the electronic circuit determines the difference between the logarithms of the detected signals. This difference is multiplied by a constant to produce a signal representative of the concentration and is displayed. The resolution of the measurement is automatically increased when the processor senses that the signals are too small.

Abstract: The invention is a moisture sensor which includes an emitter (18) to emit pulses of radiant energy toward the inside surface (14) of a window (12) at an incident angle (.theta.). The radiant energy is refracted into the window (12) at the air-inside window surface (14) and reflected off the air-outside window surface (16) back through the window (12). The radiant energy is then detected by a detector (20) at a reflection angle (.theta.') equal to the incident angle (.theta.). A support (22) spaces the emitter (18) and detector (20) a distance D between the intersection (I) of the axis (A) of the emitter (18) with the inside window surface (14) and the intersection (E) of the axis (B) of the detector (20) with the inside window surface (14) which is determined by the formula:D=2T cos .theta.(n.sup.2 - cos.sup.2 .theta.).sup.-1/2The detector (20) includes a collimator (36) to prevent non-parallel radiant energy from entering the detector (20) and an optical filter (40) to filter out radiant energy wavelengths below a predetermined wavelength in order to detect the emitted radiant energy.

Abstract: A method and portable apparatus for measuring particulate concentration in the atmosphere utilizing uniform laser pulses to traverse the atmosphere to be measured and a photo-electronic receiver which discriminates against stray light and detects the attenuation of the laser pulses. This attenuation is caused by particulates in the atmosphere which tend to scatter or absorb light. By using monochromatic laser pulses having wavelengths lying in transparent atmospheric windows, error is not introduced by the attenuation of the beam due to gases occurring naturally in the atmosphere including water vapor. Thus concentration of particulates such as smoke, fog, smog, dust and the like are measurable.

Abstract: A measuring device for immunochromatography test piece comprising an irradiation optical system for irradiating measurement light onto an immunochromatography test piece, and a detection optical system for detecting reflected light from the immunochromatography test piece under irradiation with the measurement light. The irradiation optical system comprises a semiconductor light emitting element, a beam shaping member, a lens, a first baffle portion, a second baffle portion, and a third baffle portion. The beam shaping member shapes light from the semiconductor light emitting element, into a beam of a beam section extending in a direction substantially parallel to a colored line formed on the immunochromatography test piece. The lens focuses the beam from the beam shaping member on the immunochromatography test piece. The first baffle portion removes stray light, which is disposed between the semiconductor light emitting element and the beam shaping member. The second baffle portion removes stray light, which is disposed between the beam shaping member and the lens. The third baffle portion removes stray light, which is disposed between the lens and the immunochromatography test piece.

Abstract: Motion of an object of interest, such as a cell, has a variable velocity that can be varied on a cell-by-cell basis. Cell velocity is controlled in one example by packing cells into a capillary tube, or any other linear substrate that provides optically equivalent 360 degree viewing access, so that the cells are stationary within the capillary tube, but the capillary tube is translated and rotated mechanically through a variable motion optical tomography reconstruction cylinder. The capillary tube motion may advantageously be controlled in a start-and-stop fashion and translated and rotated at any velocity for any motion interval, under the control of a computer program. As such, there are several configurations of the optical tomography system that take advantage of this controlled motion capability. Additionally, the use of polarization filters and phase plates to reduce light scatter and diffraction background noise is described.
