Dissemination visit to Agrovina fair Switzerland

Tags : 

Bird Control Group attended an Agriculture exhibition, visited by companies, agriculturists and other interested parties particularly involved in European vineyards and orchards. Sibylle Giraud, Sales manager of Bird Control Group had the opportunity of discussing the LIFE Laser Fence project at a stand which was shared with another company; IRRIP Irrigation.

Interested people discussed which animals are a nuisance in their industries. Damage is caused the most by wild pigs and birds (starling or tits). The crop loss occurred at the companies is sometimes desperately accepted and therefore is not really quantified. Regarding the amount of money the companies are losing as a result of damage, and the methods they use to disperse the animals, the answers were very vague. People say that it depends on the year, time when they animals are picking the grapes, fruit, etc. So far, the solutions for dispersing have been fencing, netting or acoustics. Some people confirm that illegal methods as toxics and shooting are also still very common. However, most of all solutions are not fully efficient or convenient to the owner of a vineyard. Obviously, they are very interested in a laser solution and are happy to hear the first results of the Life Laser Fence project. People were asking about, photographing and discussing the Life Laser Fence banner that was present at the fair.

Sibylle Giraud spoke with many owners of vineyards/orchards and with the following interested associations also:

AMTRA – An organization that focuses on doing scientific studies within the agriculture sector.

L’ASVEI – (Association Suisse des vignerons Encaveurs indépendant). This organization has 600 membersrepresenting a third of the totality of the total wine production in Switzerland.

Bio Vaud – Organizing the biggest fair for Bio Vines in Switzerland, hence they are aware of problems, issues, challenges, structure of vineyards, etcetera.

Volterra-IRIS technical meeting

Tags : 

On December 16th, members of Volterra and IRIS met at Volterra’s facilities in Palencia to discuss the technical aspects of the project. During the meeting, a conversation was also held via Zoom with Martin Sharp of LJMU, to consider several project actions to be developed in the near future.

Visit to Itacyl

Tags : 

On January 15th, members of Volterra and IRIS met with Constantino Caminero Saldaña, head of the ITACyL Pest Area at their facilities in Valladolid, to present the work being done under LIFE Laser Fence. Constantino was very interested in the project and discussed the possibility of replicating Laser Fence in collaboration with ITACyL.

A laser of many colors

The laser Fence team at Liverpool’s John Moors University has completed its launch of a “white” laser source NKT Photonics supercontinuum. The laser source will be used for the development of LaserFence systems of different colors for use in field trials.

The notion of lasers is that they are a monochromatic light source (single color). A green laser of 532nm wavelength is typically used in avian deterrence systems. This wavelength seems brighter for the human eye, but the sight of the animal can be remarkably different. So the project wants to evaluate different colors to create a laser fence.

But the supercontinuous is a real white light laser. This is not achieved by mixing red, green and blue lasers as it would be used in light shows and projection systems. This is achieved by producing ultrashort laser light pulses (PS) in a special optical fiber that is internally structured. This optical fiber “stretches” the laser of its original monochrome color in a broad spectrum from ultraviolet to infrared and is visible as a white laser beam.

The laser then passes into a filter box. This allows the light to be filtered to a specific wavelength, or color, and bandwidth, from the visible spectrum ranging from deep violet to deep red. Then this beam would be supplied by an optical fiber expander and beam to create a variable and programmable color LaserFence.
