Non-Contact Displacement Sensor: PD-704


Canon Marketing Japan Inc. launched a measurement device for making high-precision measurements of products on manufacturing lines — the PD-704 contactless measuring device.

The PD-704’s contactless measuring system utilizes a profile matching method that works by capturing consecutive images of an object and using these images (profiles) to search for correlations (matches). Based on the differences in position, the system calculates the distance and speed at which the objects have moved. Although the system is contactless, it is capable of tracking moving subjects accelerating as fast as 100G, enabling the detection of distance moved and speed of subjects when manufacturing lines are abruptly halted or drastically sped up. What’s more, thanks to an optical system that accommodates vertical shaking of ±15 mm, high-precision calculations are ensured even when shaking occurs due to changes in speed.
