摘要
The general principles of designing wide angle, large aperture optical systems are addressed. In particular, the advantages and disadvantages of reflective and refractive optical systems are discussed. it is shown that reflective optics have an inherently smaller field of view than do refractive systems. Conservation of etendue is discussed and directly applied to the determination of focal plane size of all optical systems as well as the central obscuration of systems with reflective primaries.
