Resolution Enhancement of Imaging Chips with Piezo Technology
Camera systems and scanners must have high resolutions. This creates difficulties for all applications where low light intensity means neither the resolution of the chip nor the exposure time for changing or moving objects can be freely chosen. Typical applications are fluorescence microscopy, white-light interferometry (OCT in medical technology or general surface structural analysis), or surveillance cameras and cameras for aerial photography.
Reliability and Lifetime of Multilayer Piezo Actuators
Three essential factors affect the lifetime of piezo ceramics in positioning applications: Humidity, operating voltage and temperature. PICMA® multilayer piezo actuators are based on a special PZT (lead zirconate — lead titanate) ceramic, formulated to combine the desired characteristics for motion control such as high stiffness, low electrical capacity, high specific displacement, low load and temperature dependence with exceptional reliability and long lifetime.
