Abstract

We present the dynamic analysis of a 2-axis electrothermal MEMS scanner, focusing on the step response times for random access imaging. The 1.2 mm diameter single layer silicon mirror shows rise times in the 10-40 ms range for angle changes of 0.4°-4.7°, while fall times are 5-15 ms for the same range, leading to the potential of advanced optimization path planning.
