    摘要: A method of measuring chlorophyll fluorescence is provided. The method comprises performing a first chlorophyll fluorescence measurement at one or more different areas of a crop. Performing each first chlorophyll fluorescence measurement comprises: using an actuator configured to controllably direct the light from a light source, aiming said light source at an area of the crop; using the light source to emit substantially collimated or convergently focussed light so as to irradiate the area with light; using an optical sensor, detecting chlorophyll fluorescence from the area; and using a controller, recording the location of the area. The method then comprises performing a second chlorophyll fluorescence measurement at the one or more different areas. Performing each second chlorophyll fluorescence measurement comprises: using the actuator, aiming said light source at one of said areas based on the recorded location of the area in the respective first chlorophyll fluorescence measurement; using the light source to emit substantially collimated or convergently focussed light so as to irradiate the area with light; and using the optical sensor, detecting chlorophyll fluorescence from the area.
