111. A Reference Tristimulus Colorimeter
Published: Date unknown
Author: George P Eppeldauer
Abstract: The accuracy of tristimulus colorimeters can be increased by using detector standards instead of traditional lamp standards for calibration. After high accuracy absolute spectral response determination of the color channels, spectral and amplitude c ...

113. AC-Mode SW-IR Radiation Thermometers for Measurement of Ambient Temperatures
Published: Date unknown
Authors: George P Eppeldauer, Howard W Yoon
Abstract: Recent improvements in the fabrication technology of short-wave infrared (SWIR) quantum detectors opened a new era in radiation thermometry. Ambient and higher temperatures can be measured with low uncertainties using thermoelectrically (TE) cooled e ...

114. Calibration of a Spectral Responsivity Transfer Standard
Published: Date unknown
Authors: George P Eppeldauer, Leonard M Hanssen
Abstract: A NIST-Developed pryoelectric radiometer was characterized and calibrated to extend the NIST high accuracy spectral responsively scale from the visible range to the ultraviolet (UV) and infrared (IR). The transmission of the gold-black coated LiNbO^ ...

115. Chopped Radiation Measurement With Large Area Si Photodiodes
Published: Date unknown
Author: George P Eppeldauer
Abstract: Frequency dependent response characteristics of photocurrent meters using large area, radiometric quality Si photodiodes have been analyzed. The current responsivity, the voltage noise and drift amplicication, and the gain and bandwidth of the photo ...

116. Development and Application Issues of a Spectrally Tunable LED Source
Published: Date unknown
Authors: George P Eppeldauer, Steven W Brown, G Dezsi, Irena Fryc, Yoshihiro Ohno
Abstract: A spectrally tunable solid state source based on Light Emitting Diodes (LEDs) is being developed at the National Institute of Standards and Technology (NIST). The tunable source will emulate the spectral distributions of various light sources and can ...

117. Development and Calibration of Pyroelectric Radiometer Standards at NIST
Published: Date unknown
Authors: George P Eppeldauer, Jinan Zeng, Leonard M Hanssen
Abstract: The reference spectral power responsivity scale of NIST is being extended from the silicon range to the infrared (IR) using pyroelectric radiometers. Two transfer standard pyroelectric radiometers have been developed at NIST. The main design consider ...

118. Development of a Monochromatic Uniform Source Facility for Calibration of Radiance and Irradiance Detectors from 0.2 um to 12 um
Published: Date unknown
Authors: Keith R Lykke, Ping-Shine Shaw, Leonard M Hanssen, George P Eppeldauer
Abstract: A radiometric source facility is being constructed with narrow-band, widely tunable lasers from {difference} 200nm to 12 um. The output will be highly uniform and monochromatic. This facility will be used to make a wide variety of radiometric measu ...

119. Development of the NIST Detector-based Color Temperature Scale
Published: Date unknown
Authors: George P Eppeldauer, Yoshihiro Ohno
Abstract: Based on the spectral responsivity of the channels of a tristimulus colorimeter, a color temperature scale is being developed at NIST. The low uncertainty of the spectral responsivity measurements can dominate the chromaticity measurement uncertainty ...

120. Improved Accuracy Tristimulus Colorimeters Calibrated With Standard
Published: Date unknown
Author: George P Eppeldauer
Abstract: A new method has been developed to calibrate tristimulus colorimeters for high accuracy color measurements. Instead of traditional lamp standards, modern, high accuracy detector standards are suggested for calibration. After high accuracy absolute ...
