Abstract: front page image
(EN)According to the present invention, portions of visual field areas of a plurality of imaging optical elements (15) overlap portions of visual field areas of neighboring imaging optical elements (15), and the plurality of imaging optical elements (15) include: lenses (18) which collect light (16) scattered by an object (1) to be read; apertures (19) which block portions of light collected by the lenses (18); phase modulating elements (21c) which modulate the phase of the light passing through the apertures (19); and lenses (20) which image, on an imaging surface (22), the light having a phase that has been modulated by the phase modulating elements (21c), wherein the phase modulating elements are disposed such that the resolution characteristics of the phase modulating elements in the alignment direction of the plurality of imaging optical elements (15) become consistent.
(FR)Selon la présente invention, des parties de zones de champ visuel d'une pluralité d'éléments optiques d'imagerie (15) chevauchent des parties de zones de champ visuel d'éléments optiques d'imagerie voisins (15). La pluralité d'éléments optiques d'imagerie (15) comprend : des lentilles (18) qui collectent la lumière (16) diffusée par un objet (1) devant être lu ; des ouvertures (19) qui bloquent des parties de la lumière collectée par les lentilles (18) ; des éléments de modulation de phase (21c) qui modulent la phase de la lumière traversant les ouvertures (19) ; et des lentilles (20) qui imagent sur une surface d'imagerie (22) la lumière ayant une phase qui a été modulée par les éléments de modulation de phase (21c). Les éléments de modulation de phase sont disposés de telle sorte que leurs caractéristiques de résolution dans la direction d'alignement de la pluralité d'éléments optiques d'imagerie (15) deviennent cohérentes.
