Abstract:
An autofocus imaging apparatus (200) for three-dimensional imaging on a surface of a flexible media mounted on a cylindrical drum (104) includes a carriage (210) which moves parallel to a surface of the drum and an imaging stage (208) mounted on the carriage. The imaging stage includes a displacement sensor (112) for measuring a distance to the surface of the flexible media; imaging optics (216) for producing a three-dimensional image on the flexible media; and an autofocus drive (220) for changing a focus of the imaging optics. Encoders (256, 260) provide data on the drum and carriage position. A controller (116) receives and processes data from the displacement sensor and the encoders. A computer (236) receives data from the controller, processes controller data, and transmits instructions to the controller. The controller receives computer instructions and transmits focus commands to the autofocus drive or the imaging stage.
