Is anyone familiar with the "y n u" ray trace method for optical systems, using paraxial rays where Snell's law is approximated using:
n1sinx1 ≈ n1tanx1
≈ n1u1 = n2u2
If anyone is familiar with this, I'd be interested to discuss the finer points of "a-ray" and "b-ray" tracing, as well as aperture stops, as I don't quite understand the methods involved. Thanks.
