Based on a patented light time of flight (ToF) technique, PhysDisp is a modern contactless displacement sensor. PhysDisp can consistently measure linear positions, lengths, and displacements, automatically switching ranges and resolutions depending on the proximity from and area of the marker. Connect it with the PhysLogger App or use it as a handheld standalone device.
