Abstract[English]
first-level detection arrays belonging to the same second-level detection array are added, so as to suppress N-th order harmonic components and harmonic components of orders of integer multiples of N. The optical encoder comprises the light detection device. The present application can better suppress harmonic components and is easy to design and manufacture.[French]
réseaux de détection de premier niveau appartenant au même réseau de détection de second niveau sont ajoutés, de façon à supprimer des composantes harmoniques de Nième ordre et des composantes harmoniques d'ordres de multiples entiers de N. Le codeur optique comprend le dispositif de détection de lumière. La présente demande peut mieux supprimer les composantes harmoniques et est facile à concevoir et à fabriquer.[Chinese]
