Abstract
A varifocal-type optical scanning probe including an optical fiber scanner and a varifocal lens is provided. The varifocal lens includes: a first membrane lens comprising a first lens surface with a variable curvature and a first pressure surface configured to induce a curvature variation of the first lens surface; a second membrane lens including a second lens surface with a variable curvature and a second pressure surface configured to induce a curvature variation of the second lens surface; a first pressure member disposed to apply a pressure to the first pressure surface; a second pressure member disposed to apply a pressure to the second pressure surface; and a motor configured to transmit a driving force to at least one of the first pressure member and the second pressure member.
