Actuator mechanism using suspension-wire for 2D scanning

Laser beam scanning technology has been used in various machinery such as laser beam printers, laser processing machines. Recently, the usage such as distance sensors for automobiles, area sensors for robots has expanded further. According to it, the miniaturization of beam scanning equipment, advanced features, and low-pricing have also come to be called for strongly. We suggest a method of two-dimensional beam scanning by driving a lens with an electromagnetic actuator. We use suspension wires to hold the scan lens. As a result, two-dimensional beam scanning is possible by simple structure. This paper describes the structure of the scanner module system and characteristics of the prototype model.
