Abstract:
1. A single-lens device for three-dimensional imaging of a surface of an object, comprising: a lens; a plurality of filtering apertures obstructing an optical path including the lens and configured such that light that is reflected from a surface of an object passes through the lens and the filtering apertures and is filtered to become filtered information indicative of the surface; a sensor, along said optical path and operable for capturing the filtered information indicative of the surface and producing an output signal indicative thereof; and a processor communicatively connected with the sensor for receiving the output signal indicative of the filtered information of the surface from the sensor and further configured to produce a surface image, the surface image being representative of the surface of the object, wherein said processor detects a deformed pattern from the surface, where said deformed pattern has been deformed by the surface, compares said pattern that is detected from the surface with information indicative of an original pattern prior to being deformed by the surface, and where said surface image is determined by both defocused information and also by finding, differences between the original pattern and the deformed pattern.
