Editorial
Complementary combinations By its definition, the notion of “sensor fusion” allows for the possibility of combining data from one sensing modality with virtually any other. Motion tracking provides a classic trimodal sensor fusion: The fusion of accelerometric, magnetometric, and gyroscopic data delivers precise information relative to location. In this case, the differences in the measurables that each...

Laser Safety
Advancing Laser Safety with Updates to Standard Operating Procedures It is unlikely that anyone who has read the Z136.1: Safe Use of Lasers Standard, or any of the application standards stemming from it, is unfamiliar with standard operating procedure (SOP). By definition, SOP is a formal written description of the safety and administrative procedures to be followed in performing a specific task. In laser safety, SOP typically applies to the laser system operation...
