3 OPERATING 

PRINCIPLES 

3.1 SYSTEM 

DESCRIPTION 

 
The Solartron LTX laser system uses the principle of laser triangulation to perform a one dimensional measurement of a target. This can 
be used to measure height, profile, distance, displacement, thickness, alignment etc. (For some measurement applications more than one 
laser may be required). 
 
The LTX laser projects a beam of light onto a surface which is then reflected back, a CMOS array detects the position of the returned 
beam this is then converted into a distance measurement. Auto Gain is used to adjust the laser power to be optimum for the surface being 
measured. The laser is suitable for measuring on all types of diffuse surfaces such as black, colored, metallic, wood, ceramic, steel or 
plastics. 
 
As an Orbit® product the LTX is compatible with all other Solartron Metrology Orbit products and can be used to form complex 
measurement systems combining both contact and non contact measurements. 

3.2  INSTALLATION AND SET UP 

 
The LTX operates by emitting a coherent light source and monitoring the reflected response. Using this product in environments that 
impairs optical operations will adversely affect the performance. 
 

3.2.1  Environments that are known to cause problems  

 

 Conditions 

where 

condensation is known to occur on the exterior surfaces of the LTX 

  Conditions where water is directly sprayed onto the LTX. 

  High dust or small particulate environments 

  Environments where chemicals, especially organic solvents can damage seals and glass surfaces. 

  Environments where gaseous chemicals, can penetrate seals and damage components inside the LTX. 

  Mounting in an environment where the LTX is subject to shock or vibration. 

  Mounting in areas that have a high ambient light (especially in the range 630 nm to 800 nm) (red to near infrared).
