Abstract

A scan unit for a scanning module includes a holder; a flexural member; a light scanning mirror attached to the flexural member; a magnet attached to the flexural member; and a drive coil for oscillating or vibrating the magnet, thereby oscillating or vibrating the light scanning mirror. Further, a method for making a scan unit includes inline assembling a light scanning assembly, a drive coil and a holder to one another.
