In the present study the operating distances of the LDA probe within the setup are taken into account to estimate this error. As an appropriate  evaluation criterion certain fixed paths were chosen such as the symmetry line of the flat plate, which coincides with the symmetry plane of the hemisphere (see Fig. 30). The LDA measurement volume is first set to the beginning of the measurement plane (here x/D=-1.5, y/D=0, z/D=0). Then the LDA probe is moved to the maximum traveling distance. For the symmetry line in x-direction, this refers to the coordinates x/D=2, y/D=0, z/D=0. For the vertical path in z-direction, this refers to x/D=-1.5, y/D=0, z/D=1. At the maximum traveling point of each direction the normal distance (out-of-plane distance) between the reference line and the position of the LDA probe was measured. Following this procedure, an optimum fit between the traveling distance of the measurement volume along the reference lines was found. The maximum relative error along the symmetry plane of the hemisphere is determined to be about 0.4%.

In the present study the operating distances of the LDA probe within the setup are taken into account to estimate this error. As an appropriate  evaluation criterion certain fixed paths were chosen such as the symmetry line of the flat plate, which coincides with the symmetry plane of the hemisphere. The LDA measurement volume is first set to the beginning of the measurement plane (here x/D=-1.5, y/D=0, z/D=0). Then the LDA probe is moved to the maximum traveling distance. For the symmetry line in x-direction, this refers to the coordinates x/D=2, y/D=0, z/D=0. For the vertical path in z-direction, this refers to x/D=-1.5, y/D=0, z/D=1. At the maximum traveling point of each direction the normal distance (out-of-plane distance) between the reference line and the position of the LDA probe was measured. Following this procedure, an optimum fit between the traveling distance of the measurement volume along the reference lines was found.

In the present study the operating distances of the probe within the setup are taken into consideration. As evalutation criterion certain fixed path ways were chosen such as the symmetry plane of the flat plate which coincides with the symmetry plane of the hemisphere. The LDA measurement volume is set to the beginning of the measurement plane (here x/D=-1.5, y/D=0, z/D=0). The LDA probe is moved to the maximum traveling distance. For the symmetry plane in x-direction this refers to the coordinates x/D=2, y/D=0, z/D=0, for the vertical path in z-direction this refers to x/D=1.5, y/D=0, z/D=1. At the maximum traveling point of each direction the normal distance between the reference line and the LDA measurement volume are measured. Following this procedure an optimum fit between the traveling distance of the measurement volume along the reference lines was found.
