This letter introduces a non-intrusive calibration scheme for three-dimensional (3D) optical flow velocimetry techniques. For these 3D techniques, including tomographic PIV and 3D-PTV, calibration targets need to be imaged within the measurement volume at different depth positions. However, for domains with limited access and with small dimensions, it is difficult or impossible to place a calibration target. Therefore, a non-intrusive calibration approach is proposed to overcome these drawbacks, by employing light reflections of a continuous wave laser in the measurement domain. The laser is translated to different locations, yielding a set of calibration points, comprising the spatial coordinates of the light reflections and their corresponding sensor coordinates.
