Rk. Abdrakhmanov et al., OBTAINING DIFFRACTION OPTICAL-ELEMENTS WITH A DISCRETELY VARIABLE PERIOD OF THE RULINGS ON A COMPUTER-CONTROLLED RULING ENGINE, Journal of optical technology, 64(6), 1997, pp. 603-604
This paper shows that it is possible to fabricate various types of dif
fraction optical elements (DOEs) with a discretely variable step of re
ctilinear rulings on a specially equipped ruling engine for ruling dif
fraction gratings. A schematic diagram is shown for a computer-based a
pparatus for controlling the ruling engine, and examples of the fabric
ation of certain DOEs are also given. (C) 1997 The Optical Society of
