3d scanner for minimizing motion blur

An intraoral 3D scanner comprising:

• at least one projector unit comprising:
• a light source configured for emitting light;
• a pattern generating element configured for generating a pattern of light to be projected onto a surface of an object;
• one or more camera units, operatively coupled to the projector unit, each camera unit comprising:
• an image sensor for capturing one or more image frames, wherein the image sensor comprises a two-dimensional array of pixels arranged in rows and columns, wherein the image sensor is configured for capturing a given image frame by sequentially exposing individual rows within the two-dimensional array of pixels, wherein each row is exposed for a predefined exposure time;
• and
• one or more control units configured for sequentially switching the light source on and off at a predefined frequency and for reading out a given image frame during a predefined frame readout time, during which the light source is off, wherein the light source is turned on for a predefined duration during which all rows are exposed simultaneously.
