Optical Projection Through a Lens - Geometric Imaging Diagram #196983 (License: Personal Use)

This diagram depicts the fundamental principle of geometric optics: parallel rays from point x on object plane α (at z=0) pass through lens R and converge to form the transformed image Tα′ on the image plane α′. The mapping includes coordinate representation x = (x₁, x₂) and the lens-induced transformation z(x), illustrating how spatial information is preserved or altered during imaging.
