    Abstract: An optical transmission factor is measured by using mutual measuring technology having a pair of identical units (44, 50) located on opposite sides of an object (A). Each of said units (44, 50) comprises a pair of beam splitters (47, 48), a light source means (45, 46) for illuminating an object (A) through a first beam splitter (47) and providing offset beam (56) from said first beam splitter (47), a photo-detector (49) for converting optical power from the other unit (50) and said offset beam (56), wherein each of said beam splitters (47, 48) is substantially in parallelogram shape with two pairs of confronting planes (24, 25; and 22, 23), first pairs of planes (24, 25) are not perpendicular to the second pair of planes (22, 23), one of first pair of planes (24) is mirror coated for reflecting the inside beam, so that split beams (29, 31) from single beam (27) share a common point (200) on the plane ( 23). Thus, a dust/soil free measurement with no mechanically moving means is accomplished.

    Abstract: A colorimeter for continuously monitoring the concentration of an ionic species in an aqueous solution comprises a source 30 of optical radiation, a flow cell 10 including three flow chambers 11, 12 and 13 interconnected so that a sample of the solution can pass through each flow chamber in succession, and photodetector devices 41, 42 and 43 positioned to respond to radiation transmitted through the solution in the flow chambers 11, 12 and 13, respectively. The lengths of the three flow cells are different from each other to provide a continuous real-time calibration check based upon photodetector responses to radiation transmitted through different quantities of the solution. Electronic circuitry interconnecting the radiation source 30 and the photodetector devices 41, 42 and 43 maintains the intensity of the radiation emitted by the source 30 at a substantially constant value.

    Abstract: A light transmitter transmits a beam of light along a measurement path to a light receiver which receives the light beam either directly or via a retro-reflector. The light receiver forms electrical signals representative of the transmission or absorption along the measurement path. In an arrangement with separate light transmitter and receiver units these units are arranged in respective housings at each end of the measurement path. In an alternative arrangement in which the light transmitter and receiver are in a single unit a retro-reflector is positioned at the other end of the measurement path. In this alternative arrangement the light transmitter/receiver unit is embodied in one housing and the retro-reflector in a second housing. In either arrangement both housings are sealingly closed by at least one and preferably two windows which can be moved cyclically into and out of the light beam. The transmission or absorption along the measurement path is calculated from the signals in such a way that the measured absorption is independent of the prevailing level of contamination. The apparatus is particularly useful for transmission measurements in chimneys and on airfields.

    Abstract: A method for determining a multi-dimensional profile of at least one emission parameter corresponding to an exhaust emission of a combustion process is presented. The method includes emitting a laser beam in a plurality of directions through the exhaust emission. The laser beam includes a plurality of wavelengths and the exhaust emission is characterized by the plurality of emission parameters. The method further includes detecting a plurality of absorption spectrum signals for each of the plurality of directions and determining a plurality of single-dimensional profiles corresponding to the at least one emission parameter. Each of the plurality of single-dimensional profiles is determined based on the plurality of absorption spectrum signals corresponding to each respective direction of the plurality of directions. The method also includes generating the multi-dimensional profile corresponding to the at least one emission parameter based on the plurality of single-dimensional profiles.
