Page 13: Fast Steering Mirror Technology
Fast Steering Mirror Technology Fast Steering Mirror Technology Originally conceived for military/aerospace applications such as high-speed target tracking and secure satellite-to-satellite communication, fast steering mirror technology has been developed to the point where it is economically viable for widespread commercial use in dynamic mirror alignment applica- tions. - Page 14 Fast Steering Mirror Technology Figure 2: FSM mirror head showing the eight basic components. The voice coil actuators provide the torque necessary to tilt the mirror sub- strate. Four actuators are mounted behind the mirror, one in each quadrant. Voice coils are connected in pairs along the diameter of the mirror and operate in a push/pull manner, rotating the mirror about the axis that bisects them.
- Page 15 This board processes the position information and outputs a differential voltage, A-B. This signal is sent to the FSM-CD300B controller/driver to provide the appropriate feedback current to the voice coils.
- Page 16 Fast Steering Mirror Technology Two significant advantages of FSM technology are derived from the flexure suspension: 1. FSM flexure suspension eliminates bearing surfaces often used with galvanometer scanners, and eliminates their associated stiction and wear. With bearing surfaces, stiction interrupts the smooth motion of the actuator and limits its accuracy (smallest incremental motion).

Unpacking the FSM Figure 4: Typical phase angle Bode plot for small-angle angle excitation. Amplitude 0.262 mrad. Safe Operating Area Typical shut-down curve as a function of amplitude and frequency at 20ºC. Figure 5: Continuous operation is “safe” below the line. Derate for higher ambient temperatures. - Page 22 Unpacking the FSM FSM operation is limited to an envelope of mirror deflection amplitude versus frequency. For the FSM-300, amplitude is mechanically limited to 26 mrad up to 40 Hz. Above 40 Hz, long-term, continuous operation is limited by the allowed thermal loading of the drive coils. The latter is approximately proportional to signal amplitude times frequency squared.

System Components System Components FSM Mirror Head Assembly Envelope and Mounting Interface The FSM head assembly conforms to both 1-inch and 25 mm on-center hole patterns and is configured for mounting at 0° and 45° angles on a standard optical table or breadboard. The optical axis height is 1.50” when mounted. The FSM-300head dimensions and mechanical interface are shown in Figure 9. - Page 26 System Components Figure 9: Detailed Drawing of FSM-300 Mirror Head Housing.

FSM mirror head. Prior to applying AC power, connect the system’s15-pin connector cable to the FSM mirror head and FSM-CD300B controller/driver. If you later need to remove the 15-pin connector cable, first remove AC power. Connecting and disconnecting the 15-pin connector cable in the absence of power will avoid making or breaking powered signal connections. -
Page 33: Command Inputs
System Components Once connected to the mirror head and to the wall outlet, the FSM-CD300B controller/driver may be turned on using the POWER switch located on the left side of the front panel (see Figure 16). Figure 15: 15-pin interface cable from controller to mirror head. -

System Components optimizing their application. As a practical guide, a well-defined, smooth sinewave input will generate the best output results. Self-heating of the mirror drive coils is proportional to command signal amplitude and to the square of frequency. Consult Figure 5 in the specifica- tion section of this manual for the Safe Operating Area before driving your FSM system near its frequency versus amplitude maxima. -

They are not a sign of malfunction. The FSM system does not require periodic maintenance or calibration. There is no reason for a user to ever open the FSM-CD300B Controller/Driver unit. Opening the unit would break a label and void the warranty. The only reason for a user to open the FSM Mirror Head would be to replace the mirror. -
