Abstract:
1. A lens module comprising: a first lens array comprising a plurality of first lenses; a second lens array comprising a plurality of second lenses, an optical axis of each second lens being aligned with that of the corresponding first lens; an electrostrictive member made from an artificial muscle material, the electrostrictive member sandwiched between the first lens array and the second lens array and spacing the first lens array and the second lens array, the electrostrictive member having a first surface and a second surface on an opposite side thereof to the first surface, the first surface directly adhered to the first lenses, and the second surface directly adhered to the second lenses, a thickness direction of the electrostrictive member parallel to optical axes of the first lenses and second lenses, the electrostrictive member deforming along the thickness direction thereof when an electric current is applied thereto, thereby driving the first and second lens arrays to move toward or away from each other; and a power supply being electrically connected to the electrostrictive member to provide the electric current to the electrostrictive member.
