This paper proposes a kind of computer-aided contact-type interferometer for testing the microdisplacement of piezoelectric ceramics ( ) PZT . Its accuracy is better than 0.01 m. A data acquisition system, including a CCD, grabber, etc., has been used to detect and digitize interferograms. This syst
Work has been in progress at the Bureau for several years on a reference standard lamp for testing colorfastness to light of textiles, paper, and similar materials, and on means for calibrating, in terms of this standard, the lamps used in laboratories throughout the country." The purpose is to prov
