Calibration of IR Test Chambers with the Missile Defense Transfer Radiometer

September 30, 2013
Author(s)
Simon G. Kaplan, Solomon I. Woods, Adriaan C. Carter, Timothy M. Jung
The Missile Defense Transfer Radiometer (MDXR) is designed to calibrate infrared collimated and flood sources over the fW/cm2 to W/cm2 power range from 3 m to 28 m in wavelength. The MDXR operates in three different modes: as a filter radiometer, a

PicoWatt Infrared Power Measurement using an Absolute Cryogenic Radiometer

May 7, 2009
Author(s)
Stephen Carr, Solomon I. Woods, Timothy M. Jung, Adriaan C. Carter, Raju V. Datla
We report on initial measurements of the low-temperature thermal properties of a device that is similar to the experimental apparatus used for absolute cryogenic radiometry (ACR) within the Low Background Infrared Radiometry (LBIR) facility at NIST. The

Low Background Temperature Calibration of Infrared Blackbodies

March 23, 2006
Author(s)
Adriaan C. Carter, Raju V. Datla, Timothy M. Jung, Allan W. Smith, James A. Fedchak
The Low Background Infrared (LBIR) facility at the National Institute of Standards and Technology (NIST) has performed 10 calibrations of low-background blackbodies since 2001 when the calibration facility and calibration method for low-background

Improved Broadband Blackbody Calibrations at NIST for Low-Background Infrared Applications

February 1, 2003
Author(s)
Adriaan C. Carter, Timothy M. Jung, Allan W. Smith, Steven R. Lorentz, Raju V. Datla
The Low Background Infrared (LBIR) facility at The National Institute of Standards and Technology (NIST) has continued to develop its facilities and knowledge base to meet the needs of the infrared community. Improvements in refrigeration capability at the

Radiometrically Deducing Aperture Sizes

February 1, 2003
Author(s)
Allan W. Smith, Adriaan C. Carter, Steven R. Lorentz, Timothy M. Jung, Raju V. Datla
The desire for high-accuracy infrared sources suitable for low-background seeker/tracker calibrations pushes the limits of absolute cryogenic radiometry and blackbody design. It remains difficult to calibrate a blackbody at flux levels below 1 nW/cm2 using

1-cm Collimated Source for Use in Infrared Calibrations

July 1, 2000
Author(s)
Beverly Klemme, Timothy M. Jung, Adriaan C. Carter, Eric L. Shirley, Steven R. Lorentz, Raju V. Datla
A 1 cm collimated source has been developed and tested for calibration of detectors in the 2 m to 8 m range. This source will be used to calibrate the Transfer Radiometer (BXR) currently under development at NIST. Also, the results of the test of this

NIST-BMDO Transfer Radiometer (BXR)

April 1, 2000
Author(s)
Timothy M. Jung, Adriaan C. Carter, Steven R. Lorentz, Raju V. Datla
An infrared transfer radiometer has been recently developed for the Low-Background Infrared Calibration (LBIR) facility at the National Institute of Standards and Technology (NIST) for the Ballistic Missile Defense Organization (BMDO) program. The BMDO
