Abstract :
The authors take the approach that the beam splitter design has to be carried out fully in two dimensions. They have made a number of binary phase gratings that operate in the Fourier plane, next to a focusing lens or lens pair. The elements are designed to change the single focused spot into an array of spots with a given distribution of intensity and given separation. They are only interested in the intensity distribution in the focal plane, and therefore the distance between the focusing lens and the grating is unimportant
