Abstract
A spatially coded structured light is generated by an array of laser diodes () in order to perform structured light triangulation. The laser diodes (-) are VCSEL, where the light is emitted in the direction perpendicular to the semiconductor wafer surface. Plural such laser diodes (-) are integrated monolithically to form an array (). The position of the individual laser diodes in the array is coded spatially to form a non-regular unique pattern. The light output by the lasers is projected by a refractive or diffractive optical system () into the space to be monitored to form the structured light pattern. An object () to be investigated may be illuminated by the VCSEL array () and a camera () captures the frames. A processing unit () controls the power of VCSEL (-) and processes the data from the camera ().
