Rays and Snell's Laws
Ray Tracing and Lens Analysis
Thick lens
yu Tracer and ABCD Matrices
ABCD Matrix
First-Order Ray Tracing of Multi-Element Systems
Reduced angle variable $$$ \hat u \equiv nu $$$
Reduced refraction equation
$$$ \hat u_k^\prime= \hat u - y_k \Phi_k $$$
Reduced distance variables $$$ \hat d \equiv \frac{d}{n} $$$
Reduced transfer equation $$$ y_{k+1}=y_k+\hat u_k^\prime \hat d_k^\prime $$$
y-u tabular ray tracing
Properties of the Conjugate Matrix
Conjugate condition
N12==0
Object at front focal plane
N22==0
Image at rear focal
N11==0
Afocal condition
N21==0
Relating M & N
…which gives the image location in terms of object distance and elements of M
$$$ d_k^\prime = - \frac{ d_1 A-B}{d_1 C -D} $$$
