Using Ray Matrices to Introduce Technical School and Community College
Students to Geometric Optics
The paraxial ray matrix method is an extremely simple way of performing
optical system analysis and design. Since Karl Halbach's 1964 American
Journal of Physics article "Matrix Representation of Gaussian Optics,"
a small group of optics educators have been endorsing the use of this method
for teaching technical school, community college, and university students
geometric optics. The arguments for using the matrix method are even
more powerful today.
