In photosynthesis, light energy is absorbed by light‐harvesting complexes and used to drive photochemistry. However, a fraction of absorbed light is lost to non‐photochemical quenching (NPQ) that reflects several important photosynthetic processes to dissipate excess energy. Currently, estimates of NPQ and its individual components (qE, qI, qZ and qT) are measured from pulse‐amplitude‐modulation (PAM)...
