When Should I Use an HD Sensor?

hd1

When choosing an optical displacement sensor for 2D or 3D scans there are many parameters which need to be taken into account for best results. If you approach an optical distance sensor distributor or manufacturer for a solution to your problem, he will ask you two main questions:

  1. What type of material do you need to scan?
  2. What level of accuracy is needed?

The Best Way to Scan Coin Reliefs for Minting Perfect Coins

The accuracy of a coin is completely dependent on how well the reliefs or molds are created.

If this isn’t done just right, you risk:

  • Poor quality coins
  • Coins that are not all identical
  • Enabling counterfeiting

Clearly official mints are under a lot of pressure to create measured and traceable mints.

Measuring Coins and Minting Reliefs

Here’s how to they turn a coin relief into digital data.

Challenging 3D Scans: Undercuts, Side Walls, and Inside Holes and Tubes

ConoPoint with Periscope

Ever try to use a non-contact distance measurement sensor (or optical sensor) to measure the inside of a narrow hole or tube?

How about scanning undercuts or side walls of 3D objects?

If you have, you probably know that it is not an easy task and can be expensive and complicated.  Typical triangulation-based sensors will certainly not capture these difficult shapes.  Even collinear sensors won’t be able to measure the 90° angles and hidden surfaces completely.
