ObjectGuard

Highly accurate vertical movement measurement

ObjectGuard is a free space light barrier system based on fiber optics which provides a highly precise measurement of vertical object movement. An optical head mounted on a fixed point emits a laser light which is returned by a retroreflector mounted on the surface of an object. Based on the intensity of the reflected light, a sophisticated algorithm calculates the change of vertical position with respect to the fixed point.

  • powered over the standard single mode optical fiber
  • energy harvesting by converting optical power to electrical energy
  • complex monitoring system (interrogation unit, optical head, retroreflector, data storage, and processing)

Power over fiber

The camera head is powered only by optical power delivered over the standard single mode optical fiber to ensure continuous operation.

Energy harvesting

The delivered optical power is converted to electrical energy and stored in the internal battery to power all electrical equipment in the optical head.

Complex monitoring system

The ObjectGuard provides not only an interrogation unit, optical head, and retroreflector but also data storage and basic data processing.

Advanced customization available

The monitoring system can be modified to meet your project’s needs, such as the desired functionality, interoperability, and others.

Long term field operation

ObjectGuard is highly durable and reliable even in demanding environments. This makes it especially suitable for a long term field operation.

Real-time monitoring 24/7

The unit monitors any issues that may arise in real time, alerting you immediately if necessary. Furthermore, it enables you to work with collected data right away.

Manufactured in-house

The ObjectGuard is made by Safibra, which gives us complete control over the product output, quality, logistics, production costs, and support and enables us to customize the product whenever it is necessary.

Analysis and configuration SW

The system is supplied with analysis and configuration SW, which are both platform independent and feature an embedded processing board with all decision functions.

Usage of existing fiber optic network

Installation of an expensive sensor infrastructure or availability of electrical power are not necessary.

Passive optical head

The optical head is powered over the optical fiber without any need for a power supply. Therefore it easily monitors places without electricity and hazardous or hard to reach areas.

Long distances

Optical head at the place of monitoring can be located up to 10 km from the interrogation unit. The interconnection is done using an existing optical network over standard telecom fibers.

SSH and web interface

The configuration of the system, sensors and alarms, frequency of measurements and self data logging on an integrated SSD are possible by SSH and the web interface.

Fully autonomous system

Thanks to an embedded PC and a web server running on Linux, the ObjectGuard is independent of external devices and control procedures.
