Résumé : This paper introduces a novel structured light pattern designed to be compatible with the hologram projection. Here is proposed to use a De Bruijn-based sequence and a combination of continuous and dashed lines for the pattern. Dashed lines are coded by a combination of their period and of their duty cycles. It provides 16 different lines which limits to two the required number of lines for identification. The segmentation has been made easier by inserting continuous lines between two dashed lines. As required by the use of holograms, the sequence has been adapted by making it symmetric. It has been improved by guaranteeing a hamming distance equal to two for contiguous lines. The implementation on a virtual model has shown that a subpixel accuracy has been achieved. The aim of this pattern is to be used in 3D endoscopy
