Optical device, particularly camera, particularly comprising autofocus and image stabilization

Abstract

The invention relates to an optical device (1), comprising: a first housing section (3), a cover element (20) connected to the first housing section (3), a transparent and elastically expandable membrane (10) which is arranged in said first housing section (3), a container (2) having a volume (V), wherein the membrane (10) forms part of the container (2), and wherein said container (2) is arranged in said first housing section (3), a transparent fluid (F) residing in said volume (V) of the container (2), a lens shaping part (11) that is in contact with the membrane (10) for defining a curvature-adjustable area (10c) of the membrane (10), which area (10c) faces said cover element (20), a circumferential lens barrel (50) that holds at least one rigid lens (51) facing said container (2), wherein the lens barrel is arranged in said first housing section, an image sensor (52) facing the lens barrel and the container (2), a second housing section (4), wherein the image sensor is arranged on the second housing section, and an actuator means (40) that is designed to move the lens barrel with respect to the first housing section (3) in an axial direction so as to exert a force on said membrane via the lens shaping part for adjusting the pressure of the fluid (F) residing inside the volume (V) and therewith a curvature of said area (10c), wherein said axial direction (A) is oriented perpendicular to a plane (P) along which said image sensor (52) extends, and wherein the actuator means (40) is optionally further designed to one of: moving the lens barrel (50) together with the first housing section (3) and said container (2) parallel to said plane (P); tilting the lens barrel (50) with respect to the first housing section (3) about a rotation axis running parallel to said plane (P) so as to exert a force on said membrane (10) via the lens shaping part (11) that deforms the container (2) in order to deflect light traveling through the container (2).
