Herstellung und Eigenschaften weitwinkliger optischer Interferenzerscheinungen

Abstract

Es werden genaue Vorsehriften angegeben, wie die yore Verfasser im Jahre 1911 beschriebenen weitwinkligen Interferenzerscheinungen herzustellen sind und es werden einige diesbeztigliche neue Beobachtungen mitgeteilt. In ~berein-stimmung mit den damaligen Ergebnissen wird bewiesen, daiS die elementare Lichtemission in Kugelwellen sich fortpflanzt, deren s~mtliche Teile kohSrent sind und darfiber hinaus wird gezeigt, dal] diese Wellen auch beziiglich der Intensitiitsverteilung die Merkmale einer Dipolstrahlung besitzen.

Standing-wave-excited multiplanar fluorescence in a laser scanning microscope reveals 3D information on red blood cells

“…Using the spacing between peaks in the moiré pattern, equal to L /2 n , we measured a spatial period of 4690 nm, accurate to within 3.8% of the theoretical value. Previous work has shown that when fluorescent molecules are placed close to a mirror, the emitting molecule acts as an oscillating dipole (an antenna) and that the reflected and unreflected parts of the emitted fluorescence wave interfere with each other, producing fringes from wide-angle interference 19 20 21 and oscillations in the fluorescence decay time 22 23 24 25 , with analytic expressions for the radiation patterns derived from electrodynamic theory 26 27 28 and modified further from the fixed-dipole amplitude assumption to model the fluorophore as a dipole of constant power and variable amplitude 29 30 . Subsequent work in this area studied the modulation of fluorescence intensity with distance from the mirror, and explained the modulation as a consequence of the interference effects of the excitation and of the emission being both present 31 .…”

Mind over matter: The intellectual content of experimental physics

“…This affirmation puzzled me a carried out on a rotating platform (the Sagnac experiment) was discussed as "Theoretische Physik". In that book a certain interference experiment theoretical knowledge was to be derived from G. Joos's one volume When I was a graduate student at ETH, some 40 years ago, much of our ...5 OCR Output Ac A = 4 Aw sin ¢ = 0.236 (2) which is to be compared with the prediction (A = 5700 AE, ¢ = 41°46') A = 0.230 i 0.005…”
