The paper ‘Fabrication of diffractive optical elements by programmable thermocapillary shaping of thin liquid films‘ proposed a new method to fabricate diffractive optical elements, that is, using the variable temperature distribution to induces surface tension gradients in the polymer-air interface. Gradient surface tension leads to the deformation of the interface, and the two-dimensional temperature distribution […]
