Piezo Subsystems
Johnson Electric provides linear and rotary piezo shutter products custom engineered for complex defense applications such as NUC (non-uniformity correction) and filter changers. Nanomotion brand shutters feature unique direct drive piezo technology with closed loop control, delivering silent operation and low EMI / RFI profiles. Innovative mechanical designs create the closest back-working distance and do not conflict with the footprint of the video assembly. Nanomotion piezo shutters have the best SWaP (Size, weight and power) performance for in-flight, head mounted or hand held devices. The linear and rotary shutters are ASIC closed loop controlled to maintain precision positioning of the shutter. The control electronics can be supplied as a PCBA or components for custom system integration.
