  9. Fast Steering Mirrors (FSM) - Design, Performance, And Tuning Of Piezo-Based Mechanisms 6/7/2022

    In free space optical communication (FSO), large amounts of data are “beamed” between two points – on earth, on aircraft or between satellites in space. Fast steering mirrors (FSM) are one means to compensate for disturbances that could keep the laser beam from hitting its target receiver precisely. 

  10. What Is A Gantry Stage / Cartesian Robot? 6/7/2022

    A precision gantry stage or gantry system is sometimes called a linear robot or Cartesian robot. Gantry robots typically provide overhead motion in 2 or 3 linear degrees of freedom (X-Y and X-Y-Z) and are often used for pick and place applications, 3D printing or laser machining, precision handling, and electronics applications.
