Abstract: A radiometer that incorporates multiple UV bandwidth sensors, defined in nanometers, and includes connectors for inserting a cable that is used to connect to another sensor, or to a data collection module (DCM) in a multidrop, or daisy-chain arrangement. Each sensor can be positioned at any point on a three-dimensional work piece, and will receive UV energy at the aperture having an optical component. The collected energy is directed to a detector in the sensor. A processor in the body of the sensor then computes the amount of UV radiation based on signals from the detector. This information is transferred to and stored in a data collection module to which the sensor string is connected. Data stored in the DCM can then be transferred to a computer for display purposes. The sensors and DCM can be tethered to the computer for real-time measurement readings when adjusting the UV lamps.

Abstract: Instrumentation for measuring the amount of material dissolved in a liquid solution which utilizes electro-optic technology based on the Beer-Lambert Law is implemented either as a portable, battery powered model or integrated in an automated process monitoring system. In the portable, battery powered model, a sample probe (14) is inserted into a solution to be measured. The results of the measurement are displayed on a display (22). The displayed results are frozen for a predetermined period of time at the expiration of which, the power is turned off to conserve battery power. In the automated process monitoring model, a solution loading analyzer (100) is supplied with a sample of solution to be analyzed. A probe (14) positioned in a measurement well (200) is used to determine the ratio of incident light to light transmitted through the sample. A spray nozzle (212) is used for cleaning the probe head (16).

Abstract: An ultraviolet source (14) directs selected ultraviolet radiation onto a thin film (10) to excite it. The thin film fluoresces, either naturally or as a result of adding fluorescing material. The amount of light fluoresced is proportional to the film thickness. An optical filter (16) selectively transmits fluoresced wavelengths, excluding exciting wavelengths. A photodetector (18) converts the light to an electrical signal which is processed by signal processing circuits (20) and displayed on a readout (26). The output is compensated for variations in the intensity of the exciting ultraviolet radiation by generating a second electrical signal (13', 18') proportional to the intensity of the exciting radiation and dividing the first electrical signal by a function of said second electrical signal. The compensated output is then calibrated to assure precision and accurate measurements.
