Abstract:
Apparatus and methods are described for determining the tomography and/or topography of an object. A light source generates light, and an optical element generates a 2D pattern from the light and directs the 2D pattern toward the object. An objective lens focuses the 2D pattern at an image plane, and a 2D imager acquires at least one image of the 2D pattern. The image has variable image contrast that varies according to displacement of a surface of the object from the image plane, such that maximal image contrast of the 2D pattern is achieved when the surface of the object and the image plane are coincident. A processing unit, operatively coupled to the 2D imager, derives the object's tomography and/or topography at least partially responsively to the variable image contrast of the image. Other applications are also described.

Claim (Index 25):
The method according to  claim 23 , wherein:\n generating a 2D pattern of light comprises generating a plurality of 2D patterns of light, each of the patterns corresponding to a respective light component having a respective wavelength; focusing the 2D pattern at the image plane comprises focusing the 2D patterns such that image planes of each of the 2D patterns are at respective locations that are a known function of the wavelength of the corresponding light component; acquiring at least one image of the 2D pattern comprises acquiring a plurality of images of the 2D patterns,\n each of the images corresponding to a respective 2D pattern, and corresponding to light of a corresponding, respective wavelength, at a corresponding, respective image plane, and \n each of the images having variable image contrast that varies according to displacement of a surface of the object from the respective image plane such that maximal image contrast of the 2D pattern is achieved when the surface of the object and the respective image plane are coincident, and \n deriving the selected characteristic of the object comprises deriving the selected characteristic of the object, at least partially responsively to the variable image contrast of each of the images.
