摘要：

A photosynthetically active radiation (PAR) sensor has been described and tested, the sensor is so small that it can be placed directly on a leaf in the canopy. It is inexpensive to produce and several can be used in the canopy at the same time to obtain realistic measurements of irradiance distribution. Its characteristics satisfy the PAR sensor requirements, and correlation to a standard commercial sensor is better than 0.97. Spectral response, cosine relationship, stability and calibration are described, as well as its construction and electronics. (C) 1999 Elsevier Science B.V. All rights reserved.
