US 2026/0110894 A1 · DOUBLE LENS-BARREL DEVICE

Abstract

A double lens-barrel device includes a first lens barrel, a second lens barrel, an intermediate connecting portion and a distance detecting element. The intermediate connecting portion is disposed between the first lens barrel and the second lens barrel. The first lens barrel is fixed to the intermediate connecting portion. The second lens barrel is movable with respect to the intermediate connecting portion for changing the distance between the first lens barrel and the second lens barrel. The distance detecting element is only disposed between the second barrel portion and the intermediate connecting portion to detect a change of distance between a first optical axis of the first lens barrel and a second optical axis of the second lens barrel. The first optical axis and the second optical axis are perpendicularly connected to a reference line.
