Laser Range Finding

When the laser rangefinder is activated, a series of extremely short laser pulses from the transmitter are sent through the smaller objective lens to the target (multi-pulses). At the target, the laser light is reflected back. The main part of the laser light is absorbed or diffusely reflected by the target and only a very small percentage of the light is reflected back to the LRF module. This little remaining laser light is received by the bigger objective lens and focused onto the proprietary receiver diode. The receiver diode starts sampling the echo at a very high frequency and together with our sophisticated measuring algorithms it allows the Laser Range Finder Module to calculate a reliable distance – even if only few laser lights were reflected. 

Vectronix is one of the few truly integrated Fiber Laser Manufacturing companies on the world. We have two different versions of Fiber Lasers (LRF 6019 & LRF 7047) and they are all fully developed and produced here in Heerbrugg, Switzerland. By ourselves we developed our own transmitter electronics as well as the matching receiver electronics to get the optimal performance out of our Laser Range Finder Module. 

When integrating or handling a module, be careful with ESDS: The LRF module is sensitive to electrostatic discharge. Do not touch any electronics or components unless protective measures are first applied. For the integration, EMC disturbances should be avoided, as they can cause incorrect measurements or even no measurements. To avoid or reduce emitting noise, noise susceptibility and coupling between sources and receptors, the LRF module can be mounted inside an electrical shielded housing. 

Yes, it is possible to mount and operate our Fiber Laser Modules (LRF 6019, LRF 7047) with the Laserbox detached, to minimize the front area. To do this, a special mounting set is required. This set contains a Flexcable, a Flexcable Securing Clip and Mounting Screws with washers.

The Laser Range Finder Modules LRF 6019 and LRF 7047 are equipped with a 1550nm laser for the distance measuring and optionally with an 830nm laser pointer. This pointer is built directly into the laser measuring system and uses the same fiber and same optics as the 1550nm laser. If this option is chosen, the boresighting of the complete LRF module can be done easily by just aligning the 830 nm pointer, as this aligns automatically also the 1550nm laser, which is responsible for the distance measuring). 

To make the laser spot of the 830 nm laser pointer visible, a standard NIR camera or a night vision device can be used. These devices are significantly cheaper than a 1550 nm camera. By using a boresight chart at a defined distance, the LRF can be aligned by bringing the main optical axis of the host system and the LRF to the predefined positions on the boresight chart.

Magnetic North Finding

The Magnetic Disturber Detection (MDD) gives feedback on whether the compass is influenced by external magnetic disturbers. If activated, the DMC displays a “Probability Value” in percent, which is calculated based on history data, precisely from last 12-point compensation procedure. The value indicates the whether a measurement is disturbed more than a given value.

The System State Compensation (SSC) is a feature unique to the DMC-pico only. This is a software which allows the removal of influences due to magnetism for different states in host system. This can save the integrator from expensive last-minute design changes. And the good thing is that no additional hardware is required.

Example: The host system has different operational states. Instead of performing / saving / restoring a 4- / 12-point for each state, just do one compensation and measure once the “deltas”, then restore the deviations based on the host system state (= added / removed disturbers).

Example states are: Camera on / off, battery powered / remote powered

Yes, here we recommend using the DMC-pico as it measures within a range of 360°. This means that the line of sight is fully under the control of the user.
