A method of producing an inline hologram lens is disclosed which includes the steps of producing a diffracted wave beam by a diffraction device, producing a spherical wave beam by an optical device, providing the diffracted wave beam perpendicularly incident on a photo-sensitive layer as a reference wave beam, simultaneously providing a spherical wave beam perpendicularly incident on the photo-sensitive layer as a subject wave beam through the diffraction device, and developing the photo-sensitive layer to produce an inline hologram lens.

Method for manufacturing in-line hologram lens

An electro-mechanical transducer having a first layer made of piezoelectric material having opposing major surfaces, a pair of electrodes formed on the major surfaces of the first layer, respectively, and a second layer clamped at its one surface to one of the surfaces of the first layer. In this case, the first layer has a Young's modulus of E, the second layer has a Young's modulus of Ex in one direction and a Young's modulus Ey in the direction perpendicular to the one direction in the major surface, The Young's moduli E, Ex, Ey satisfy the relation E&gt;Ey, Ex&gt;Ey, and one end of the first and second layers along the one direction is clamped.
