Infrared quantum ghost imaging illuminates living plants but doesn’t disturb them
Experimental setup and photon pair correlation. Credit: Optica (2024). DOI: 10.1364/OPTICA.527982 The study, published in the journal Optica, demonstrates live plant imaging of several representative plant samples, including the biofuel crop sorghum. Using a new detector, researchers obtained clear images of living sorghum plants in light much dimmer than starlight. This advancement enables imaging of delicate and light-sensitive samples such…
