Abstract and Figures This paper highlights based on author's experience how optics and photonics is applied in Thai agriculture. Optical sensors are available that measure and record data about crops and soil in real time by using the reflectance of light shined on growing plants. 17, no. Unfortunately, agriculture is also believed to be the main cause of climate change, biodiversity loss, and degradation of land and fresh water [2]. Popular commercialized daylighting systems include heliostats, solar tubes, and skylights. Electron beam and plasma technology are key techniques in many industries. 80, pp. In this application, light distribution uniformity was not the most important factor as a uniform, but low, amount of light would not be useful. 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. A profitability comparison of GHs and VFs indicates that there is a slight economic preference toward the VF [4].

Estimation of rice neck blasts severity using spectral reflectance based on BP-neural network.Acta physiologiae plantarum33.6 (2011): 2461-2466. There is a very wide range of optical sensors applied in agriculture, which goes from sensors used to 2. To test their discrimination model, researchers tested hundreds of samples. Their aim was to detect spectral regions where rice reflectance changed depending on rice neck blast disease index and to select the key wavelength bands with the sensitivity to analyze disease severity and validated their neural network-based spectral model for qualifying disease severity. Plants contain pigments that have an affinity to photons of particular wavelengths, and photons of a particular wavelength have different energy levels. The efficiency of converting photovoltaic energy back into visible radiation is less than one percent, while the unconverted use of the solar radiation in the visible range is reported to be 50% [11]. WebVision-based machine and robotic systems are anticipated to play a larger role in the agriculture industry in the near future. Meanwhile, food production is predicted to decrease [2]. However, there is little research looking specifically at indoor agriculture applications. A reduction in utility energy requirements for artificial lighting in a VF model reduces operating expenditures and would create an appealing business proposition. Some examples include the detection of aflatoxins in corn, late blight disease, or yellow leaf curl virus in tomatoes, leaf spot or powdery mildew in sugar beets, yellow rust in wheat, and countless other crop diseases that affect yield and quality. The biggest drivers of food demand --population and income-- continue to rise. This information enables early warning of unfavorable climate conditions and accurate assessments of crop damage. Optics and photonics technologies have proven to be effective tools for applications like imaging, spectroscopy and spectral imaging. Photonics is finding applications in all aspects of agriculturereducing the use of chemicals via smart pest control and selective spraying, reducing waste, protecting wildlife, and helping farmers shift to science-based procedures that maximize yield and profit while minimizing harm to the environment. This method can be utilized as a free source of energy for indoor applications. WebPrecision Agriculture and Hyperspectral Sensors: Monitoring Against Drought, Disease, and Nutrient Stress Crop monitoring for nutrients, water-stress, disease, insect attack and overall plant health is a vital aspect of successful agricultural operations. A laser processing tool is only as good as the motion equipment underneath it. This study assessed the light distribution (i.e., uniformity and intensity) of poly(methyl methacrylate) (PMMA) optical fiber at two different diameters (3mm and 20mm). 3, 2017. Both methods utilize two different PMMA optical fiber sizes (2 3mm and 20mm) at five different heights (6, 8, 10, 12, and 14 in) to determine the effect of height on both light intensity and light uniformity. For the empirical findings, light intensity was measured by the light spectrometer at 2in. Keep it simple - don't use too many different parameters. Introduction.

A pioneer in novel real-time sensing techniques (near-infrared [NIR] and Raman spectroscopy, and hyperspectral imaging) based on integrated photonics for agri-tech is OnePlanet Research Center, IMEC, based in the Netherlands. The unit of measurement is called the photosynthetic photon flux density (PPFD) and is defined as micromoles per square meter per second (mol/m2/s). It was time-consuming and nearly impossible for large-scale operations to perform comprehensive visual inspections. This paper aims to present a comprehensive review of three photonic techniques, namely imaging, spectroscopy and spectral imaging, in a 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. Numbers tell a straightforward story regarding agricultures environmental impact. There is a very wide range of optical sensors applied in agriculture, which goes from sensors used to 2. Agriculture is responsible for 70% of global water use, 24% of greenhouse gas emissions, and environmental degradation on a planetary scale.2 It is now apparent that boosting food production using current practices is unsustainable. 7369, pp. For example, while the average light intensity for a 20mm cable for all heights was above 50Lux (Figure 7), the intensity of the light for the 2 3mm cables for all heights was less than 10Lux (Figure 8). The Fraunhofer FEP possesses a proven method for efficiently freeing seed products, foods, and animal feed of pathogens within a matter of seconds. WebOptics and photonics are revolutionizing applications within the agriculture industry. This method is a strategy often used in both modern and ancient architecture and can reduce the energy consumption in buildings associated with artificial lighting with the additional benefit of visual comfort [8]. A subset of an OFD system is the hybrid lighting system (HLS) which encompasses the OFD architecture by appending artificial light to support consistent lighting levels through controlled dimming [12].
