1. A borescope, comprising:
a housing;
an ultrasound sensor configured to rotate about a first axis;
a controller configured to receive measurements from the ultrasound sensor to determine a volume of a borehole in which the borescope is located; and
a motor configured to move the ultrasound sensor along the first axis to a plurality of axial positions, wherein the ultrasound sensor is configured to take a plurality of distance measurements at a plurality of angular positions, respectively, about the first axis at each axial position among the plurality of axial positions along the first axis.
