22. Calibration and Characterization of UV Sensors for Water Disinfection
Published: 1/2/2006
Authors: Thomas C Larason, Yoshihiro Ohno
Abstract: Ultraviolet radiation (UV) effectively inactivates common pathogens found in ground and surface waters such as Cryptosporidium, Giardia, and most bacterial pathogens (e. g., E. coli). Water treatment facilities recently started using ultraviolet rad ...

26. Using the Substitution Method with a Monitor Detector will Improve the Accuracy of Absolute Spectral Power Responsivity Measurements
Published: 11/1/2001
Authors: Sally Skidmore Bruce, Thomas C Larason
Abstract: Many radiometric, photometric, and colorimetric applications require the determination of the absolute spectral power responsivity of photodetectors. The absolute spectral power responsivity is the ratio of the photodetector's output (in amperes ...
