These videos show 2 sets of polysilicon surface micromachinied micromirror arrays designed and fabricated by QinetiQ that passed static white light interferometric inspection. On a simple actuation test, significant differences are apparent.
The first video shows a number of devices fail (significant non-uniformity in motion)
