The compound diffraction grating in the Ivory Optomechanical Modeling Tools

摘要

The author's previous work describes the simple diffraction grating in which the plane of incidence at the grating's substrate is orthogonal to the lay of the grating. This work develops the equations for the general case where the lay of the grating is rotated with respect to its surface normal so the direction of the desired diffraction order is a compound angle in the grating's coordinate system. The optomechanical constraint equations are developed and an example of their application is shown.
