Santa Barbara Infrared (SBIR) produces high performance resistive emitter arrays for its line of IR Scene Projector (IRSP) products. These arrays operate in modes supporting up to 400 hertz frame rates. The physical properties of the microelectromechanical emitter pixel structures cause the transition times for temperature slewing to be well over the 2.5 milliseconds required to support 400 hertz operation. This paper expands on a study previously conducted by SBIR to determine the maximum capability of a technique in which the pixel drive of the first frame of a commanded transition is modified to improve transition time. This technique is referred to as overdrive and in this study it was effective in reducing rise and fall times from as much as 6 milliseconds to 2 milliseconds.
