1. A method for using a single-lens device for three-dimensional imaging of a surface of an object, comprising acts of: providing an imaging lens, an aperture configured to generate distinguishable images, a sensor, and a processor; transmitting light containing object information through the imaging lens and the aperture such that the transmitted light produces distinguishable images on the sensor; generating a plurality of distinguishable images, each of the plurality of distinguishable images including point information of the surface of the object; calculating distance information from the point information between the distinguishable images; and using the processor and distance information to generate a representation of the object.
