I am considering a non-conventional (non-projector) use of a TI DMD part. Application would use a DLP660 (or other DMD part) in the focus plane of an imaging system. In one mode, all micro-mirrors will be in 'on' state and I'd like to re-image the reflected image off the DMD part onto a 2D image sensor. Essentially forming a typical image system for a short period of time. To assess image quality in this application I need to know what the typical distribution of 'on'/'off' angles one can expect from a given DLP660 part. Part-to-part mean mirror 'on'/'off' angles are given in the DLP660 specification, but I need to get some metric on what the variability (e.g. angle distribution) of micro-mirror 'on'/'off' angles are within a particular DMD part. For example, 95% (2 x sigma) of all mirrors will be +/- 0.1 degrees around the mean mirror angle.
Any help would be greatly appreciated.
