1. A system for optical measurement of an object, the system comprising:
a radiation generating device configured to emit electromagnetic radiation onto the object;
a capturing device including an image sensor, wherein:
the capturing device is configured to capture a measurement image as a result of an exposure of the image sensor with radiation returned from the object, and
the capturing device is configured to vary a focus setting during the exposure; and
an evaluation device configured to determine coordinates of at least one location on a surface of the object based on the captured measurement image.
