\begin{abstract}
To study the orientation-dependence of the diffraction patterns of the
reflective grating, we utilize the cylindrical screen. Experiments show
the curved, expanded and inclined diffraction patterns.

The textbook-screen in the grating experiments is a planar screen and
the diffraction orders distribute linearly in one dimension. The
cylindrical screen visually shows that the diffraction orders of a
rotating reflective grating distribute in two dimensions. The CCD can be
placed at the accurate locations of each order to collect data. By using
the cylindrical screen, only two coordinates are needed to describe the
curved/expanded/inclined diffraction patterns of the rotating reflective
grating. The cylindrical screen may be used to test the theories of the
grating rotating around 3 axes.%
