Paper Abstract

In free space optical communications (FSO) systems, fast steering mirrors (FSMs) are commonly used for closed loop tracking. Newer, lighter-weight and lower-power consumption, MEMS devices are also being considered for beam steering applications. Since FSO systems have to be capable of operating under a variety of conditions, robust components are needed to withstand the various temperatures and other environmental factors. This paper reports on thermal measurements over a temperature range of -40°C to 60°C that were made to show operational capability and to highlight any systematic issues associated with the operation of various commercially available, high-speed beam steering mirrors.
