Расчёт Преломляющей Поверхности Для Формирования Изображения В Виде Линии

A method of designing a refracting surface to generate a line-shaped image is presented. A relationship for the surface is derived as an envelop e of family of cartesian ovals. The refracting surface that generates the imaginary picture of the line-segment is presented as an approximate solution of the problem of generating the rectangular directivity diagram.
