New applications with 3D sensing technologies are entering the market every day. Based on diffractive optical elements, structured light is a key factor to realize computer vision based sensing solutions. Active alignment can compensate uncertain tolerances during early stages of the product development, which eases prototyping and ramp up of production. Built upon a customizable micromanipulator design, a specialized part handling system with integrated measurement and UV curing capabilities has been designed. We will discuss our production solution and alignment algorithm and present how it can be scaled for high volume production.
