Nl. Kazanskiy et al., APPLICATION OF A PSEUDOGEOMETRICAL OPTICAL APPROACH FOR CALCULATION OF THE FIELD FORMED BY A FOCUSATOR, Optics and Laser Technology, 28(4), 1996, pp. 297-300
The present work deals with the application of pseudogeometric optics
techniques to calculating a light field generated by a focusator of la
ser radiation into the rectangular domain, We have derived an analytic
al expression for the principal term of the asymptotic expansion in th
e focal plane including the geometric-optics shadow domain. Copyright
