What Is a Pockels Cell?
A pockels cell is a device used for measuring pressure by converting the deformation of piezoelectric elements inside the cell due to pressure changes into an electrical signal.
Known for its compactness and lightness, it finds wide applications across industries, automotive, medical fields, and more. The operating principle involves placing piezoelectric elements inside the cell, which deform in response to pressure changes. The amount of deformation is converted into an electrical signal and ultimately translated into pressure. Pockels cells are employed in various fields such as industrial machinery control and monitoring, automotive engine and brake control, medical equipment control, and others.
The basic structure includes piezoelectric elements, converters, amplifiers, and displays. The piezoelectric elements deform in response to pressure, the converters convert this deformation into an electrical signal, amplifiers amplify the signal, and finally, the pressure is displayed on the display.
