Three-dimensional (3D) shape measuring technology based on laser system has been utilized for many industrial applications. The 3D shape measurement is essential for the inspection and evaluation of the industrial products due to promise the product safety. To date, the importance of compactness, mobility, and high speed measurement on 3D shape measuring technology have been gradually increased. For 3D shape measurement, we have developed the inner profile measuring technology by use of a ring beam device which is consisted of a laser diode and a conical mirror, and high speed phase shifting technique which is based on fringe projection of spatio-temporal conversion. The 3D shape measurement technology has been available to industrial applications such as automobile, energy plant and heavy industry. This report is focused on medical applications for 3D shape measuring technology based on laser systems, such as total hip arthroplasty, prosthetic socket evaluation, and 3D position registration in radio treatment system.
