Accuracy of two dimensional interferometers

  1. Mar 30, 2014 #1

    the accuracy of interferometers for finding emitting direction in one direction is given as:

    Δθ = Δφ•λ/(2pi•l•cosθ)

    but what would it be if two dimensional accuracy is required, something like interferometer in crossing?

    I thought this could be found somewhere in Internet, but I just don’t have luck.

    I don't understand the physical setup and what you are trying to find.

    This angular error is only valid for one dimension. I wonder what is the combined angular error if two crossed inteferometers are used.

    Are you suggesting a two dimensional (rectangular) array or just a pair of crossed linear arrays?
