It is not the first time that I read the paper "Fabrication of freeform optical components by fluidic shaping", but I have to admit that I did not get a very good understanding of it. This time, at least I can throw some questions to myself and offer a certain way for the next step […]
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 […]
