![]() ![]() ![]() However, all realistic sources are partially coherent. Such a field, which is perfectly spatially and temporally coherent, has wavefronts corresponding to surfaces of constant phase. For a mono-energetic complex scalar wave, the situation is clear: the “phase” is equal to the argument (“arg”) of the complex function describing the field. ![]() It may surprise you that there is some confusion as to the meaning of the term “phase”, in the context of propagation-based phase retrieval. Propagation-based phase retrieval, namely the recovery of the phase of a forward propagating (and typically paraxial) optical field from intensity measurements over one or more planes perpendicular to the optic axis, is of importance for a variety of radiation and matter wavefields. Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored.Use a comma to separate multiple people: J Smith, RL Jones, Macarthur.Use these formats for best results: Smith or J Smith.For best results, use the separate Authors field to search for author names.Use quotation marks " " around specific phrases where you want the entire phrase only.Question mark (?) - Example: "gr?y" retrieves documents containing "grey" or "gray".Asterisk ( * ) - Example: "elect*" retrieves documents containing "electron," "electronic," and "electricity".Improve efficiency in your search by using wildcards.Example: (photons AND downconversion) - pump.Example: (diode OR solid-state) AND laser.Note the Boolean sign must be in upper-case. Separate search groups with parentheses and Booleans.Keep it simple - don't use too many different parameters. ![]()
