"Because of the small scale, hinge fatigue is not a problem" What is the physical reason for this?--84.188.176.54 22:54, 12 February 2006 (UTC)

[edit] Graphic

I have a hard time picturing the scene; I think a graphic would really help a lot here.

Each [mirror] is mounted on a yoke which in turn is connected to two support posts by compliant torsion hinges. In this type of hinge, the axle is fixed at both ends and literally twists in the middle. [...] Two pairs of electrodes on either side of the hinge control the position of the mirror by electrostatic attraction. One pair acts on the yoke and the other acts on the mirror directly.

So each end of the yoke is connected with a torsion hinge to a support post, and the mirror is mounted on the middle of the yoke? On either side of the hinge we have two pairs of electrodes; does that mean we have eight electrodes per hinge, and since we have two hinges per yoke, overall 16 electrodes per mirror?

Here's one I found on Google images. There are four electrodes per mirror. The green pair acts on the mirror, the brown pads at the bottom act on the yoke. --Dtcdthingy 19:45, 30 August 2006 (UTC)

Thought you all would like to know that this article was referenced in the current issue of Physics News Update, specifically, issue #797. Erzahler 19:42, 16 October 2006 (UTC)

[edit] EEtimes interview, contains history

There is an interesting interview with Larry Hornbeck at EETimes. It can be used as a source for much of the historical information. - Davandron | Talk 17:01, 25 January 2007 (UTC)
