Concept to Commercialization of an Artifact for Evaluating 3D Imaging Systems per the ASTM E3125- 17

June 29, 2018
Author(s)
Balasubramanian Muralikrishnan, Prem K. Rachakonda, Vincent D. Lee, Katharine M. Shilling, Daniel S. Sawyer, Geraldine S. Cheok, Luc Cournoyer, Joe Gleason
The newly released ASTM E3125-17 standard describes several point-to-point distance tests to evaluate the performance of spherical coordinate 3D imaging systems, commonly referred to as terrestrial laser scanners (TLS). The relative-range error test, which

FT-IR Based Polarimeter with High-Quality Brewster-Angle Polarizers

October 8, 1998
Author(s)
Simon G. Kaplan, Leonard M. Hanssen
A Fourier transform infrared (FT-IR) spectrometer based broadband infrared polarimeter has been developed around a pair of high-quality Brewster angle polarizers. These polarizers consist of four Ge plates in a chevron geometry and have been measured to

Microstuctural Characterization of Hardened Steel by Nondestructive Methods

July 1, 1997
Author(s)
P T. Purtscher, B Igarashi, Donna C. Hurley, K W. Hollman
This paper describes the application of a variety of methods to the nondesctructive characterization (NDC) of microstructure in hardened steels. The measurements include ultrasonic velocity, nonlinear ultrasonics, resonant ultrasonic spectroscopy (RUS)
