Color exciting images of marauding dinosaurs, and assemble them into giant posters!
Kids will love coloring these 24 action-packed scenes of pterodactyls, triceratops, and other mammoth monsters. The prehistoric creatures wreak havoc in two different settings-on the streets of a modern city and on the plains of a mythological battlefield. Pages are perforated for easy removal, and simple instructions explain how to assemble them into two 32 x 32 inch posters.


The Ray And Wave Theory Of Lenses

Calculations on lens systems are often marred by the unjustifiable use of the small-angle approximation. This book describes in detail how the ray and wave pictures of lens behaviour can be combined and developed into a theory capable of dealing with the large angles encountered in real optical systems. A distinct advantage of this approach is that Fourier optics appears naturally, in a form valid for arbitrarily large angles. The book begins with extensive reviews of geometrical optiks, eikonal functions and the theory of wave propagation. The propagation of waves through lenses is then treated by exploiting the close connection between eikonal function theory and the stationary phase approximation. Aberrations are then discussed, and the book concludes with various applications in lens design and analysis, including chapters on laser beam propagation and diffractive optical elements. Throughout, special emphasis is placed on the intrinsic limitations of lens performance. The many practical insights it contains, as well as the exercises with their solutions, will be of interest to graduate students as well as to anyone working in optical design and engineering.
