Claim One:
1. A focus scanner for recording surface geometry and surface color of an object, the focus scanner comprising: a multichromatic light source configured for providing a multichromatic probe light for illumination of the object, a color image sensor comprising an array of image sensor pixels for capturing one or more 2D images of light received from said object, wherein the focus scanner is configured to operate by translating a focus plane along an optical axis of the focus scanner and capturing a series of the 2D images, each 2D image of the series is at a different focus plane position such that the series of captured 2D images forms a stack of 2D images; and a data processing system configured to derive surface geometry information for a block of said image sensor pixels from the 2D images in the stack of 2D images captured by said color image sensor, the data processing system also configured to derive surface color information for the block of said image sensor pixels from at least one of the 2D images used to derive the surface geometry information.
