Charged particle beam diagnostics is a key task in modern and future accelerator installations.
The diagnostic tools are practically the \eyes" of the operators. The precision and resolution
of the diagnostic equipment are crucial to dene the performance of the accelerator. Transition
and Diraction Radiation (TR and DR) are widely used for electron beam parameter monitoring.
However, the precision and resolution of those devices are determined by how well the production,
transport and detection of these radiation types are understood. This paper reports on simulations
of TR and DR spatial-spectral characteristics using the Physical Optics Propagation (POP) mode
of the Zemax advanced optics simulation software. A good consistency with theory is demonstrated.
Also, realistic optical system alignment issues are discussed.
