This is in the range of ordinary laboratory diffraction gratings. For red light of wavelength 600 nm, this would give a first order diffraction maximum at about 22° .

Figure 2.2: Schematic LEED pattern for Si{111}1x1. Closed circles represent the diffracted beams for which the indices are noted. Reciprocal lattice directions and mesh are indicated. On a typical LEED screen, this would correspond to a 100eV pattern. ... Back to the List of Figures ... Back to the experimental chapter...

Second Order Diffraction; Most Hyperspectral imaging systems operate as a spectrograph where the angle of incidence is fixed. Therefore, the general diffraction grating equation simplifies to (See "Imaging Spectrometer Fundamentals.pdf )

The problem of second-order wave diffraction around arbitrary two-dimensional bodies is studied and a numerical method in time-domain presented. The solution is based on separating the velocity potential into a known incident velocity potential and a scattered velocity potential.
