多功能植物光合表型成像測量系統

多功能植物光合表型成像測量系統PlantExplorer采用創(chuàng )新的多光譜葉綠素熒光/可見(jiàn)光成像技術(shù)，利用的LED技術(shù)、CCD技術(shù)、通信技術(shù)，實(shí)現了對植物表型的創(chuàng )新測量，可以在獲取RGB成像、葉綠素成像、花青素成像的同時(shí)，獲取葉綠素熒光成像（成像面積53cm x 53cm）。系統包括帶光學(xué)濾光輪的CCD成像系統、聚焦系統、嵌入式高亮度紅光LED、光譜白光LED、多光譜LED、嵌入式電腦和觸摸屏。由于采用一個(gè)CCD加濾光輪的組合，使得能夠在像素水平上進(jìn)行圖像疊加計算。

多功能植物光合表型成像測量系統PlantExplorer包括三個(gè)版本：標準版PlantExplorer、高級版本PlantExplorer^Pro和適合高達120cm植物的版本PlantExplorer^Pro+。三個(gè)版本都可以選配GFP和/或RFP成像模塊（需在購買(mǎi)時(shí)指出，不可后續升級），其中PlantExplorer可以在購買(mǎi)后，再后續升級成PlantExplorer^Pro。
