Vision Sensor

The vision sensor is the image-processing measurement sensor for Optiv measuring machines. It can perform non-contact measurements on the smallest features subject to the tightest tolerances, inspecting where a probe cannot. It is ideal to avoid deformations when working with delicate materials.

The object being measured is captured through the lens on a matrix camera (CCD camera). The optical signals are converted into a digital image and further processed to calculate the coordinates of measured points using the imaging processing routines in PC-DMIS Vision.

The vision sensor achieves the highest optical precision through the design of its telecentric optics. The advantage of this principle is that the size of the object on the image (image scale) remains constant, even if the working distance changes within the telecentric space. The distortion produced by telecentric optics is substantially less than that from non-telecentric optics.
