Height Measurement of microbumps using a whitelight triangulation …

WebA structured-light 3D scanner is a 3D scanning device for measuring the three-dimensional shape of an object using projected light patterns and a camera system. [1] The light source from the scanner head projects a series of parallel patterns onto the scan target. When light projects onto the object's surface, the patterns become distorted. WebThe projection and imaging model of microbumps illuminated by the light plane at different positions during the scanning process was analyzed. The microbump height is computed … blue ridge document shredding https://bobbybarnhart.net

WebDiffraction and Interference. We know that visible light is the type of electromagnetic wave to which our eyes responds. As we have seen previously, light obeys the equation. c = f λ, where c = 3.00 × 10 8 m/s is the speed of light in vacuum, f is the frequency of the electromagnetic wave in Hz (or s –1 ), and λ is its wavelength in m. WebLight emitted toward a corner cube repeatedly propagates regular reflections and the reflected light ultimately moves straight back toward the emitted light. This is referred to as retroreflection. ... Triangulation. Distance-settable Sensors generally operate on the principle of triangulation. This principle is illustrated in the following ...
