Abstract
The output signal of microtranslators such as PZT is not always proportional to the input signal. It usually is expensive and requires special techniques for linearization. A method is described that is simple, inexpensive, and accurate for measuring the length variations of PZT. A commercialized load cell is directly attached to a PZT (the output voltage of the load cell versus the expansion of PZT has very good linearity) and is then applied to the scanning mechanism for a laser scanning microscope (LSM). A sampling circuit for the increasing voltage used to produce sampling pulses is also studied.
