1. A shaft alignment apparatus for statically aligning a first shaft with a second shaft, comprising:

  • a first dual-axis position sensing detector providing a first signal;

    a second dual-axis position sensing detector providing a second signal;

    first mount means for mounting the first dual-axis position sensing detector to the first shaft;

    second mount means for mounting the second dual-axis position sensing detector to the second shaft;

    a first alignment radiation source mounted on the first mount means and oriented to provide a first alignment radiation beam to the second dual-axis position sensing detector to generate the second signal;

    a second alignment radiation source mounted on the second mount means and oriented to provide a second alignment radiation beam to the first dual-axis position sensing detector to generate the first signal; and

    a readout means having defined alignment conditions and being responsive to the first signal and the second signal for visually displaying shaft alignment, whereby with adjustment of the first shaft with respect to the second shaft, alignment of the first shaft with the second shaft will be indicated on the readout means according to the defined alignment conditions.
