Interferometric Distance Measurement
- Sensor Heads
Next to relative and absolute distance measurement, vibration analysis is possible with a 25 kHz bandwidth in free space or glass rods & fibers as cavities.
|Confocal displacement sensor|
|< 0.05 nm signal stability, no periodical artifacts|
|Absolute distance measurement|
|0.03 … 20 m working distance|
|25 kHz bandwidth|
|3 sensor axes, multiple devices|
|Flexible fiber-based sensor heads|
|Position and angles|
|Velocity and acceleration|
|Beam interrupt compensation|
|Gap and edge measurement in layered structures|
All applications require different constrains for collimation, focusing and the beam profile, depending on their reflecting targets. The shaping of the laser beam is achieved by different sensor heads. All these sensor heads for quDIS are based on optical fibers, well-established in the telecommunication market.
Next to standard collimators and established focusing heads, qutools designs special heads for applications in harsh environments.
