This article provides an overview of several software control applications developed for NASA using LabVIEW. The applications covered here include (1) an Ultrasonic Measurement System for nondestructive evaluation of advanced structural materials, an Xray Spectral Mapping System for characterizing the quality and uniformity of developing photon detector materials, (2) a Life Testing System for these same materials, (3) and the instrument panel for an aircraft mounted Cloud Absorption Radiometer that measures the light scattered by clouds in multiple spectral bands. Many of the software interface concepts employed are explained. Panel layout and block diagram (code) strategies for each application are described. In particular, some of the more unique features of the applications' interfaces and source code are highlighted. This article assumes that the reader has a beginner-to-intermediate understanding of LabVIEW methods.Roth, Don J. and Parker, Bradford H. and Rapchun, David A. and Jones, Hollis H. and Cao, WeiGlenn Research Center; Goddard Space Flight CenterCOMPUTER PROGRAMS; VIRTUAL REALITY; MEASURING INSTRUMENTS; SOFTWARE DEVELOPMENT TOOLS; BLOCK DIAGRAMS; SPECTRAL BANDS; RADIOMETERS; APPLICATIONS PROGRAMS (COMPUTERS)
This guide describes how to implement modern GUI (Graphic'ser Interface) methodologies within the LabVIEW application. The book provides interface design strategies and basic graphic design principles, and includes over 100 step-by-step LabVIEW GUI Code examples.
