摘要： 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.

摘要： A device for measuring the optical turbidity, i.e., the soot components in discharge gases of diesel engines, which is relatively simply constructed, operates safely and enables a simple handling even with differently structured measuring devices. This result is achieved in that a controller for controlling the light density of the measuring light beam is optically coupled with a light source. A sample and hold circuit is provided with the values of a measuring detector and the control detector fed to a sample and hold circuit in a time multiplex manner with the measuring values processed in a computer unit. Control values are fed to the light source by means of a control loop. In addition, the computer unit is capable of storing a plurality of measuring values or turbidity values and average value of the stored peak values, whereby the peak values are determined by a dynamic measuring of a defined number of measuring cycles. Moreover, a device is provided which feeds motor related parameter to the computer unit for triggering of measuring value determination and measuring value calculation.

摘要： An apparatus for detecting defects in a laser mirror by using a laser beam in order to detect any possible changes in reflectivity over the surface of the mirror. A laser beam is split by a beam splitter into one portion for scanning the mirror to be inspected and which is reflected therefrom to produce a reflection signal, the remaining portion of the beam providing a reference signal. A computer receives both signals and on the basis of comparison thereof determines the condition of the mirror because there will be incorrect reflection of the laser beam from any region of the mirror which is defective.

摘要： This invention relates to an optical absorptiometer which is characterized by a light source unit of a broad wavelength having a source of constant energy which is collimated into two light beams, one of which is transmitted through the liquid to be measured, and another beam which is transmitted through a conductor and acts as a reference beam, and a detector unit which contains two photocells, one photocell for measuring the beam transmitted through the liquid to be measured, and another photocell which measures the reference beam, a position in the absorptiometer for optically placing the liquid to be measured between the source unit and the detector unit, and means for measuring the energy difference between the light beams of the measured liquid and the reference beams in terms of absorbance, and means for converting this result to an electrical signal. In the preferred embodiment, the constant energy in the light source is controlled by feedback circuitry; the reference beam is transported by a fiber optic cable to the reference photocell of the detector unit; water condensation on the optical and viewing windows is prevented by means of dry air flow; the electrical signal is displayed and/or relayed to control an operation; and the reference beam is a segment of the original light beam from the source.

摘要： A spectrophotometer is shown in which a deuterium lamp emits a plurality of frequencies of interest the beam passes through a filter for selecting the wavelength of the light desired to be incident onto the sample and then onto a beam splitting plate which diverts a relatively small friction of the beam to a first reference photocell. The remaining portion of the beam then is incident directly on a sample tube. The sample tube may be so designed that its transparent walls form a lens focusing the beam on the sample to be tested. The beam then passes through the further wall of the sample tube and is detected by a second testing photocell, the output of which may be compared to the output of the reference photocell to provide a signal indicative of the relative amplitude of the testing beam. The reference photocell may be used to insure that the intensity of the beam incident on the beam splitter remains constant over time so that values output by the testing photocell may be comparable to measurements taken at a later time, without the use of a reference sample for calibration purposes. A sample cell is provided which allows the use of the instrument of the invention in on-line applications in high pressure systems. A particularly preferred method of mounting the deuterium bulb is also shown.

摘要： An analyzer compensation circuit for compensating for the fluctuations in the intensity of the light source or for stains on the windows of cells in an analyzer. A pair of D-A converters are respectively connected to compensating and measuring light detectors. An up/down counter is arranged to count either up or down in response to the output of a comparator. The comparator compares the output of the D-A converter connected to the compensating detector with a reference value and the output of the up/down counter is connected to both of the D-A converters such that the output of the converter connected to the compensating detector is adjusted to be equal to the reference value. Since the other D-A converter is also connected to the output of the up/down counter, the output of the other D-A converter has been compensated for fluctuations in the light intensity or stains on the windows on cells used in the analyzer.

摘要： In order to avoid the encumbrance of a rotary mirror scanner by large calating radiation sources for intermittently illuminating the detector element of the scanner, a supplementary radiometer responsive to the same scene as is scanned is absolutely calibrated by intermittent illumination from calibrating sources that are conveniently small. The calibrated radiometer signal is compared to portions of the scanner output responding to the same object field, for calibration of the scanner output. The radiometer may be scanned at right angles to the direction of scan of the scanner in order to provide calibration of both the forward cross lines and rear cross lines alternately scanned by a stereoscopic scanner, for stereoscopic observation of cloud formations, land masses, air traffic distribution or the like from a space craft.

摘要： In the disclosed device, a sensor produces a corroborating signal when a computer flash unit emits a flash proper for an exposure. A timer energizes an indicator for a predetermined time in response to the corroborating signal. When the sensor produces a subsequent corroborating signal in response to another flash, while the indicator is energized, a reset device resets the timer. According to one embodiment of the invention, an overriding arrangement connected to the timer nullifies the operation of the timer a predetermined time after a flash emission.
