Bosch, the company known for automotive parts, also has a division that builds power tools. One of their most interesting product lines is a set of laser range finders. The model on the left is a DLE 50. The red button triggers the laser, and a set of optics and an optical sensor triangulate the distance to a visible red laser dot. It can measure distances up to 50 meters with an typical accuracy of a 1.5 millimeters.The model on the right, the DLE 150 Connect, provides a few more features. Range is up to 150 meters. It also comes with Bluetooth connectivity, allowing it to send measurements to Windows laptops or Windows Mobile PDA's.
They use some of the same optical principles as the Velodyne LIDAR I discussed in an earlier post. They also have a nice industrial design with a tough enclosure and a large button that gives a bit of a kick when triggered. That's great for users who are wearing thick gloves. Unfortunately, these range finders do not yet seem to be available in the US.
For purposes of full disclosure, I must add that at the time I posted this blog, I worked for the Bosch corporation at its research lab in Palo Alto, California.
