Frequency Domain Modal Estimation Techniques, Experimental Techniques

January 1, 1998

Author(s)

S Fahey, Jon R. Pratt

In this brief, we discuss the estimation of modal parame-ters using single-degree-of-freedom approximations. Then, we proceed to review two multi-degree-of- freedom techniques for modal parameter estimations-the first based on dynamic matrices and the

High Accuracy Aperture Area Measurement Facilities at the National Institute of Standards and Technology

January 1, 1998

Author(s)

J B. Fowler, R Durvasula, Albert C. Parr

The uncertainty in the measurement of aperture area can limit high-accuracy radiometric and photometric measurements. Relative total uncertainties in some measurements have now been determined at or below the 0.1% level, making substantially smaller
