Burke B.F., Quantum Interference Paradox, Nature, 223, $389-390,$ 1969.

-------------------------------------------------------------
There is no direct physical process of addition "of waves / photons"
passing through "slots or telescopes" in VLBI!
-------------------------------------------------------------

The interference fringes (picture) in VLBI (interferometer) is pure
mathematical abstraction, since the construction of an interference
pattern is carried out in the computer.

Dear colleagues physicists!

Whether you can describe / solve in more detail problems
of a self-interference of a photon in VLBI:

1. "Detections" of signals? ;
2. "Recording" of signals? ;

....

and so on?

Dear colleagues, be sure and not hide in obscurity

There are two theories of interpretation of an interference phenomenon of electromagnetic radiation: 1. A wave point of view and 2. A photon point of view. 1. A wave point of view. The problems does not exist for classic wave interpretation of an interference phenomenon in VLBI an interferometer. http://groups.google.com/groups?selm...n.jpl.nasa.gov 2. A photon point of view. From a photon point of view, the photon can be gripped by one and only by one radio telescope from two radio telescopes of VLBI. $$**********************************************[/itex] Now Dear colleagues! you should describe YOURS the physical mechanism of a self-interference of a photon in VLBI. $**********************************************$$ From my point of view, you can not describe the physical mechanism of a phenomenon of a self-interference of a photon in VLBI, since any your "interpretation" will be foregone to contain logic and physical ERRORS of explanation of the physical mechanism of a phenomenon of a self-interference of a photon in VLBI. --- Best Regards Aleksandr Timofeev ===================================================== P.S.

I would name this type of an interferometer as an interferometer with independent registration of signals in shoulders. Fundamentally any other interferometer by nothing differs from an interferometer considered below. Principles of work VLBI The microwave interferometr with superlong basis consists of two radio telescopes were on a very large distance from each other. Before experiment or after him, the nuclear hours are synchronized. Each radio telescope writes on a videotape a transformed radiation accepted by an antenna. Simultaneously with a signal, the scores of time received from the standard of frequency, are written on a videotape. After ending experiment we have two videotapes with entries of a signal and scores of time. The "interference picture" is received after data processing of these videotapes on the computer. There are two graphic schemes illustrating the description: The microwave interferometer with superlong basis. Part 1.

Our interferometer has the right and left shoulders. The distance between shoulders does not influence sensitivity of an interferometer. The sensitivity of an interferometer to a signal is determined by the worse receiver from both radio telescopes. - The distance between shoulders of an interferometer can be no matter how large. (This problem is reduced to a problem of transportation of clocks of a synchronization). 2. The addition of signals is carried out in the computer, that allows to apply no matter how complicated algorithms of addition of signals. - In that specific case, we can arbitrary vary delay of signals in each from a shoulders in any direction. Conditionality of physical concept " an Interference picture ". Here we shall be convinced of a celebration of a principle of a causality. The events happening on slots of an interferometer have primary significance, all other events happening in an interferometer have the status secondary. Let's analyze physical concept addition of signals in an interferometer. The radiation incident on an input of an interferometer has the following performances: Wavefront; Frequency band; Spectral fluence of energy; For each frequency: Polarization; Amplitude; Phase; Stability. The interferometer considered by us, is an interferometer with independent registration of signals in shoulders and the process of addition of signals is carried out in the computer. The phrase " process of addition of signals is carried out in the computer " allows clearly to seize essence " concepts of an interference picture " and source of an origin of this concept. In the given type of an interferometer there is some arbitrariness in choice by us of the law of addition of signals from the right and left shoulders. In our case " the kind of an interference picture " depends on the concrete law of addition of signals selected by us. In other kinds of interferometers geometry (physical) construction of an interferometer determines the law of addition of signals and " a kind of an interference picture ".
