How Angle Sensors Work
Multifunctional Joint Angle Sensor
The multifunctional joint angle sensor measures the obliquity and orientation of a joint using a tube with a radius as the only required parameter. It reconstructs angular parameters based on voltage outputs on each sample position.
Compact 3D Angle Sensor
The compact 3D angle sensor uses an optical method for three-dimensional angle measurement. It calculates the angle based on the position of the light source and the angle of the reflected light.
Three-Dimensional Laser Angle Sensor
The three-dimensional laser angle sensor uses the diffraction theorem and ray optics analysis to measure small angles in three dimensions. It projects a laser beam onto a surface and measures the angle of the reflected light.
Multi-Beam Angle Sensor
The multi-beam angle sensor uses multiple beams of light to measure the 3D profile of a cylindrical surface. It projects the beams onto the surface and measures the angle of the reflected light.
Steering Angle Sensor
The steering angle sensor measures the steering wheel position angle and rate of turn in vehicles. It is placed in the steering column of the vehicle.
Optical Angle Sensor
The optical angle sensor uses an optical frequency comb laser to measure the angle between two surfaces. It measures the absolute distance between the surfaces, lateral chromatic aberration, or second harmonic generation.
