Coefficient of thermal expansion of the components are in harmony, comprises a replaceable mirror, large scan angle and low wobble, Tote-band resonant scanner

摘要

Taut-band resonant scanner, including (12) subassembly (10) elongated strips is disclosed. The length in the longitudinal direction, width and perpendicular to the width direction, has a thickness perpendicular to the thickness direction in both the longitudinal and transverse direction to the longitudinal direction, thickness than the width of the elongated strips substantially smaller, longitudinal and transverse direction, define a plane width / length of the strip. And attached to a portion of the strip, the sub-assembly includes a (14, 16) half divided in two parts. Thermal expansion coefficient of the strip is the same as that of the mounting structure of the housing.
