Avantes has been working with the US Department of Agriculture on projects to measure grains during harvest. Techniques of precision agriculture are alternatives to optimize the use of inputs, among them nitrogen. The technology can result in less chemical use and lower environmental impact. From the illumination side, the quartz tungsten halogen (QTH) lamp is a popular choice in hyperspectral imaging because it provides broad spectral illumination from VIS-IR to shortwave-infrared (SWIR). In this study, rice showing a moderate disease index exhibited high raw reflectance in the 805-1000 nm range, while rice with a higher disease index demonstrated a lower raw reflectance under 940 nm but higher reflectance in the 960-1000 nm range. However, there is little research looking specifically at indoor agriculture applications. As climate change has heavily affected agriculture, smart agriculture that uses various optical sensors based on spectroscopy could be used to detect biotic and abiotic stresses of the plants early. A variety of functions can be implemented through thin-films technologies in optics, lighting and interior as well as through novel systems for connected mobility. An experiment was performed to compare the performance between two 20mm optical fibers with and without an UV filter. NIR spectroscopy is one advancement that has tremendous potential for agricultural applications. The electricity usage for lighting a VF outweighs a GH, but that is negated by high consumption of electricity for GH heating, ventilation, and air conditioning (HVAC) [4]. One of the recent examples is within vertical farming, which can save up to 98% of soil and 95% of water required for farming.3. Improve efficiency in your search by using wildcards.

To meet these challenges, Ibsen Photonics (Denmark) developed their PEBBLE NIR spectrometer (see Fig. Heat management dissipation is also needed, which leads to a high-power consumption, and form factor constraints limit the imaging design, size, and cost of the hyperspectral system. One-man operations will turn into medium- or large-scale businesses. CV measures the repeatability and reproducibility of the data. WebVision-based machine and robotic systems are anticipated to play a larger role in the agriculture industry in the near future. Different varieties of plants need different types of light intensity and distribution, and thus cables and height settings may be selected to best match the specific needs of a particular plant. Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored. Two optical fibers spanning 54 feet were mounted exterior to a storage container and routed to the interior of the structure and coupled to a shelf in close proximity. Laser processing applications that leverage laser scan heads are especially susceptible to errors from thermal loads. In general, optical fiber daylighting systems utilize optical fibers as a light delivery method.

A Japanese OFD system named Himawari concentrates and collects sunlight by utilizing multiple Fresnel lenses and sun-tracking and then distributes that light into buildings using optical fiber [9]. Operating an indoor agricultural business continues to be a challenge. Their ultimate aim is to develop fully autonomous systems with autocalibration to help make agriculture more sustainable. The scenarios were first modeled and tested using lighting simulation software. This was similar to an earlier study that correlated moderate fungus infection with high reflectance in the SWIR 1135-2400 nm range and low reflectance in the NIR 709-1134 nm range and a more serious fungal infection with low reflectance under 1297 nm and a high reflectance between 1298 and 2400 nm.

Thus, it is necessary to address both economic and plant growth challenges in the use of artificial light. In this application, light distribution uniformity was not the most important factor as a uniform, but low, amount of light would not be useful. Although these technological developments will be a critical factor in enhancing future agricultural productivity, for Global Zero Hunger to become a reality, continuing action will also be required to address other challenges affecting the global food supply chain, namely population growth, deterioration in soil quality, climate change, deforestation, production of carbon dioxide, and decreasing biological diversity.
