How does laser level sensing work?

In a small area without critical accuracy requirements, the old school approach of a stretched string with a chalk line and a bubble level can provide adequate measurements. For larger, more critical situations, laser technology provides a substantial improvement. A laser, such as the DeWalt DW074KD, a rotary laser level accurate to 1/4 inches at […] The post How does laser level sensing work? appeared first on Electrical Engineering News and Products.
