Optimet ConoProbe single-point measuring sensor

Supported hardware devices

• The ConoProbe is a robust optical sensor for high precision distance, 2D profiles and 3D measurements
• Link to manufacturer's website: http://www.optimet.com/index.php

Supported platforms

• Windows 32 bits

This device is not included in any of the standard packages

The device manufacturer supports additional platforms. On request, Plus toolkit will be extended to support this device on other platforms, too.

Installation

• Need to install the Smart32 SDK from here.

Device configuration settings

• 
  Type = "OptimetConoProbe"
  
• 
  ToolReferenceFrame
  

  Default = "Tracker"
• 
  LocalTimeOffsetSec
  

  Default = "0"
• 
  AcquisitionRate
  

  Default = "100"
• 
  LensOriginAlignment Defines the position of the lens origin w.r.t. a tracking tool. Defined as the unit vector (dx, dy, dz) pointing in the direction of the laser beam and the translation from the tracking tool origin to the lens origin (lx, ly, lz): [dx, dy, dz, lx, ly, lz].
  

  Default = "1.0 1.0 1.0 0.0 0.0 0.0"
• 
  DelayBetweenMeasurements The time between successive measurements in micro seconds.
  

  Default = "1"
• 
  Frequency The measurement working frequency.
  

  Default = "1000"
• 
  CoarseLaserPower The measurement coarse laser power.
  

  Default = "13"
• 
  FineLaserPower The measurement fine laser power.
  

  Default = "0"
• 
  DataSources Exactly two DataSource child element are required.
  
  • 
    DataSource
    
    • 
      PortName
      
      • Measurement The measured distance, either as the raw sensor measurement in mm (in all of the translation elements of the matrix), or aligned with the lens origin (using the LensOriginAlignment parameter described above).
      • Parameters Raw sensor measurements: Distance (mm), Signal-to-noise ratio (%) and Total. The values are stores in the translation part of the matrix (m(0,3) = Distance, m(1,3) = SNR, m(2,3) = Total). These values should only be used as a means of acquiring real-time parameter info.
    • 
      BufferSize
      

      Default = "150"
    • 
      AveragedItemsForFiltering
      

      Default = "20"
