(optikai) útkülönbség optical path difference Explanation: http://www.britannica.com/EBchecked/topic/430459/optical-pat... Aspects of the topic optical path difference are discussed in the following places at Britannica. Assorted References * light waves and lenses (in optics: Seidel sums) ...the y0 coordinate lying in the meridian plane containing the object point and the lens axis. The departure of the wave from the ideal sphere is generally called OPD, meaning optical path difference. It can be shown that OPD is related to x0 and y0 by five constants S1 through S5, and the quantity... http://www.szgti.bmf.hu/opto/Opto_folia/P4b/Elmelet/CDFIZ.rt... A leképezés minőségének tehát kifogástalannak, un. diffrakció limitáltnak kell lennie, amit úgy fejeznek ki, hogy az átlagos hullámfront torzulás OPDRMS (Optical Path Difference Root Mean Square) nem lehet a hullámhossz 0.07 század részénél nagyobb (Marechal kritérium), hiszen az OPU valójában egy miniatűr interferométer. |

path length difference Explanation: Az úthossz "path length". Lehet a "difference in path length" fordulatot is alkalmazni. Figyeljünk azonban arra, hogy ténylegesen úthosszról, vagy optikai úthosszról van-e szó. Ez utóbbi ugyanis az úthossz szorozva a törésmutatóval (optical path length). http://en.wikipedia.org/wiki/Interference_(wave_propagation) http://en.wikipedia.org/wiki/Optical_path_length -------------------------------------------------- Note added at 8 mins (2010-03-19 10:46:01 GMT) -------------------------------------------------- "Abstract Path length difference is the key parameter in two-beam interferometer, especially in low coherence interferometer. It determines the visibility of the interference fringes. In this study, we present a method to determine the path length difference between two arms of a fiber optic Mach–Zehnder interferometer by evaluating the peaks of power distribution of the interference spectrum with a wide band light source. The experimental results are in close agreement with the theoretical calculations."
