Dynamic measurements of distance, velocity or acceleration

For dynamic measurements of distance, velocity and acceleration the linear optics should be used. Necessary components are:

  •  Laser head
  •  Power Supply
  •  Linear interferometer IL1
  •  Linear retro-reflector RL1

Dynamic measurements of distance, velocity and acceleration require optical elements IL1 and RL1 to be aligned along laser beam as shown in the figure below. The laser measures the difference of distance between optical elements (i.e. IL1 and RL1).  During dynamic measurements the usage of the air temperature sensor is recommended. Base temperature sensors do not have to be used.squareness

Dynamic measurements can be performed not only along the laser beam but also in directions perpendicular to the laser beam. These configurations are shown in the figures below. In those two configurations only the retro-reflector RL1 can be moved.

Dynamic measurements of angle

For dynamic measurements of angle the angular optics
should be used. Necessary components are:

  • Laser Head
  •  Power Supply
  • Angular Interferometer IK1
  •  Angular Retro-reflector RK1

Dynamic measurements of angle require optical elements IK1 and RK1 to be aligned along laser beam as shown in the figure 13.5. Each of the elements can be moved. During Angular straightness measurements the usage of the air temperature sensor is recommended. Base temperature sensors do not have to be used.

Angular straightness measurements can be performed not only along the laser beam (as shown in the figures below) but also in directions perpendicular to the laser beam. These configurations are shown in the figures 13.7 and 13.8. In those two configurations only the retro-reflector RK1 can be moved.

Dynamic measurements of straightness (Wollaston)

dynamic4

For dynamic measurements of straightness the Wollaston optics should be used. Necessary components are:

  •  Laser Head
  • Power Supply
  • Wollaston prism WP2
  •  Wollaston retro-reflector WRP2

Dynamic straightness measurements require optical elements WP2 and WRP2 to be aligned along laser beam as shown in the figure above. Each of the elements can be moved. During dynamic straightness measurements the usage of the air temperature sensor is recommended. Base temperature sensors do not have to be used.  Dynamic straightness measurements can be performed in two configurations – horizontal X or vertical Z. In the configuration X only the straightness of path in the X axis is measured. The same situation is with the Z setup.
