1. An intraoral scanner for determining 3D geometry and color of at least a part of the surface of an object in an oral cavity, the intraoral scanner comprising:
a tip configured to be inserted into the oral cavity,
a light source in optical communication with at least one camera sensor of the intraoral scanner, such that the light source in combination with the at least camera sensor is configured to record different colors,
a pattern generator in optical communication with at least one camera sensor of the intraoral scanner, such that the pattern generator in combination with at least one of the at least one cameras is configured to record a probe light with a plurality of configurations in the form of a static illumination pattern, and
a hardware processor configured to:
determine the 3D geometry based on the probe light and the static illumination pattern, and
determine the color of at least a part of the surface by combining the different recorded colors.
