Using optical fibers to measure absorption in intact conifer leaves relative numbers of chloroplasts and pigment content

摘要

The experimental setup. Absorption spectra were collected using a fiber-coupled light source, two optical fibers, and an array spectrophotometer. The tips of the fibers were in physical contact with the leaf on each side and shared a common cylindrical axis by using a plastic tube (blue) with a perpendicularly drilled hole for holding the leaf (green)
