Geometrical camera calibration with diffractive optical elements

Optics Express, 2008
Traditional methods for geometrical camera calibration are based on calibration grids or single pixel illumination by collimated light. A new method for geometrical sensor calibration by means of diffractive optical elements (DOE) in connection with a laser beam equipment is presented.

Glass Difractive Optical Elements (DOEs) with complex modulation DLC thin film coated

Materials Research, 2008
We developed a complex (amplitude and phase) modulation Diffractive Optical Element (DOE) with four phase levels, which is based in a glass substrate coated with DLC (Diamond Like Carbon) thin film as the amplitude modulator.

Fractal checkerboard zone plates

Results in Physics
In this work, we introduce a novel diffractive optical element, the Fractal Checkerboard Zone Plate (FCZP). It is based on a two-dimensional binary matrix generated through iterative substitution rules that produce self-similar fractal geometries ...
