Abstract

é revelado um escâner 3d para gravar a topografia 3d de um objeto, incluindo o escâner 3d: - uma unidade de projeção configurada para projetar um feixe de luz de sonda estruturado sobre o objeto; uma unidade de geração de imagens disposta para adquirir imagens 2d do objeto quando o objeto é iluminado pelo feixe de luz de sonda estruturado; e - uma unidade de acionamento disposta para controlar a posição do feixe de luz de sonda estruturado no objeto rodando uma parte móvel da unidade de projeção em torno de um eixo de articulação, a unidade de acionamento incluindo um motor de rotação compreendendo ou disposto para acionar uma roda, onde a superfície da roda que é operativamente acoplada à parte móvel da unidade de projeção tem uma distância radial do eixo do motor de rotação que muda com a rotação.
