​

1. Artificial Evolution Research Institute (AERI)https://www.aeri-japan.com/) provides solutions for national resilience, global warming prevention, and sustainable social infrastructure. By installing a measurement module, we irradiate an ultra-high-power femtosecond laser (AERI/HEL) developed by our laboratory from a satellite and observe plant chlorophyll fluorescence from the satellite to measure the photosynthetic activity of vegetation (plant/forest activity). can be evaluated.

​

2. This solves the limitations and uncertainties of the conventional method using passive stationary chlorophyll fluorescence, and directly based on (1) fluorescence spectrum shape change and (2) time change (lifetime) of fluorescence waveform during pulse-induced fluorescence. Actively extracting plant physiological and ecological information such as plant pigments and photosynthetic activity, and estimating and evaluating plant/bioresource cultivation environment (specifically, crop growth condition, harvest time/yield amount). becomes possible. As a result, it will be possible to achieve innovative technological evolution that will enable the construction of a sustainable and environmentally friendly economic society (Sustainable Bioeconomy) that utilizes plant and bioresources.

3. Artificial Evolution Research Institute (AERI)https://www.aeri-japan.com/) provides solutions for national resilience, prevention of global warming, and realization of sustainable social infrastructure. , using a laser-induced fluorescence lifetime (LIFL) measurement module consisting of a multichannel spectrometer, an optical oscilloscope, an optical spectrum analyzer (OSA), a streak camera, etc., (1) fluorescence spectrum shape change and (2) pulse-induced It measures the time change (lifetime) of the fluorescence waveform etc.

​

4. Information on the type and amount of components in the body of the plant can be obtained from the above (1) change in the shape of the fluorescence spectrum. And (2) from the time change (lifetime) of the fluorescence waveform when induced by a pulse, the energy transfer, charge transfer speed, and We can obtain plant physiological and ecological information on the photosynthetic reaction process depending on the redox state of the reaction center and the actual situation of the component molecules. This makes it possible to estimate/evaluate the plant/bioresource cultivation environment (specifically, the growth condition of agricultural crops, harvest time/yield).

​

5. Artificial Evolution Research Institute (AERI)https://www.aeri-japan.com/) provided as optional equipment for the national resilience solution, the above experimental results show that large-scale farms and vast areas such as the Amazon, which are difficult for humans to inspect, can be implemented by implementing the above-mentioned satellite optoelectronic technology application laser-induced plant fluorescence measurement module. It will be possible to obtain estimated indicators such as water stress during plant growth in forests and jungles and the amount of components in leaves by remote sensing from artificial satellites.

​

6. In addition, sunlight-induced plant fluorescence is an indicator of the photosynthetic capacity of ground vegetation (photosynthetic capacity: photosynthetic rate measured under ideal conditions where environmental factors do not limit photosynthesis). can also be estimated. This makes it possible to estimate/evaluate the plant/bioresource cultivation environment (specifically, the growth condition of agricultural crops, harvest time/yield).

​

7. Furthermore, by using the above-mentioned satellite optoelectronic technology application laser-induced plant fluorescence measurement module, various phenomena such as urban atmosphere of carbon dioxide and methane, forest fires, and variations due to transport on a correlated scale can be detected and atmospheric transport models can be developed. It also has the effect of making it possible to estimate regional fluxes by inversion analysis.

​

8. In addition to carbon dioxide, methane, water vapor, and sunlight-induced plant fluorescence, the satellite optoelectronic technology-applied laser-induced plant fluorescence measurement module also enables estimation and verification of carbon monoxide. By installing it together with the satellite optoelectronics application infrared (IR) spectroscopy/FT-IR spectroscopy laser remote sensing module, it becomes possible to estimate and verify the greenhouse gases that cause global warming. .
