CALDIRO: contactless & low-cost embedded system for on-board vibration measurement

DESCRIPTION

• Based on optical feedback interferometry (“self-mixing” effect), the laser is used as light source, micro-interferometer and detector at once, resulting into a low-cost integrated system
• Coupled with an accelerometer measuring the laser sensor own movements, the device is robust to parasitic vibrations

APPLICATIONS

• Non destructive testing applications:
  - Operating industrial conditions
  - Embedded applications
