Abstract
Systems and methods are provided for acquiring images of objects. Light of different types (e.g., different polarization orientations) can be directed onto an object from different respective directions (e.g., from different sides of the object). A single image acquisition can be executed in order to acquire different sub-images corresponding to the different light types. An image of a surface of the object, including representation of surface features of the surface, can be generated based on the sub-images.
