Piezoelectric closed-loop motion modules are integral to the Dynamic Ionosphere CubeSat Experiment (DICE) satellite funded by NSF
We all are familiar with the consumer digital cameras that are in our pockets, mobile phones and personal computers. Thanks to incredible advances in microelectronics, CMOS image sensors and optics, most of us have a very good camera within reach most of the time.
Now these tiny cameras are inspiring product engineers in “non-consumer” applications—such as biometric identification, medical and diagnostic devices, and machine vision—to make even greater products. In fact, markets for these new applications are projected to grow faster than consumer camera markets over the next few years.
In this article we discuss sensor and lens requirements, compare the M3-F focus module to voice coil motors and stepper motors, and talk about image processing, digital signal processing and other system considerations.
