Egge, Akram, Kartashov, Welde, Tong, Österberg, and Aksnes: Errata: Sinusoidal rotating grating for speckle reduction in laser projectors: feasibility study

This article [Opt. Eng. 50, 083202 (2011)] was originally published on 4 August 2011 with errors in the equation appearing on page 3, paragraph 2, line 7. The correct equation is:

[TeX:] \documentclass[12pt]{minimal}\begin{document}\begin{equation*} s_i ^{(n)} (N) = ({\rm 2}R_1 i/d)\,{\rm sin}(\pi n/({\rm 2}N)).\end{equation*}\end{document} si(n)(N)=(2R1i/d) sin (πn/(2N)).
The corrected manuscript was published online 31 August 2011 and it appears correctly in print.
