The current proposal aims the development and fabrication of electrically variable liquid crystal lenses for 3Dx000D
digitization. Namely, this type of lenses already has been successfully applied to mobile (cell phone) camerasx000D
to perform auto focus function without mechanical movements. In the same time, the 3D digitization gainsx000D
more and more attraction along with 3D printers which become broadly accepted in the R&D and prototypingx000D
community. One of the techniques, used to perform the 3D digitization, consists in projecting parallel lines onx000D
objects and capturing the resulting images by using several cameras. In current products, the user needs tox000D
move the hand to ensure that the image is in focus. Thus, the goal of this project is the development of liquidx000D
crystal lenses that would ensure that the images are always in focus even in the video mode (in contrast to cellx000D
phone's point & shoot application). As part of this project we will try to adapt the lenses that our group hasx000D
developed for mobile cameras to this technique of 3D projection that have different technical requirements. Asx000D
a result, we shall develop, build, characterize and integrate (in collaboration with our industrial partner)x000D
electrically variable liquid crystal lenses for their 3D digitization device.
