Zusammenfassung:	The present disclosure relates to a single pattern shift projection optical system for a 3D scanner, which shifts and projects a pattern image for 3D scanning.The single pattern shift projection optical system for a 3D scanner of the present disclosure comprises: a plurality of light sources each emitting light in different constant wavelength bands; a pattern member that transmits only a portion of the light generated from each of the plurality of light sources as patterned light; and a refracting member disposed on a path of light passing through the pattern member to refract and transmit the patterned light.
