Embodiments of the present invention may be used to perform measurement of surfaces such as external and internal surfaces of the human body in full field and in 3 D. An electromagnetic radiation source may be configured to project the electromagnetic radiation in a pattern corresponding to a spatial signal modulation algorithm. The electromagnetic radiation source may also be configured to project the electromagnetic radiation at a frequency suitable for transmission through the media in which the radiation is projected. An image sensor may be configured to capture image data representing the projected pattern. An image processing module may be configured to receive the captured image data from the image sensor and to calculate a full field 3 D representation of the surface using the captured image data and the spatial signal modulation algorithm. A display device may be configured to display the full field 3 D representation of the surface.
