Design Guidelines
Our design framework focuses on three things: cost, ease of use, and portability. A traditional fluorometer is highly sensitive to fluorescence readings and can detect changes in the microseconds. This allows for specific fast biological mechanisms to be measured indirectly, however, highly increases the cost. To overcome this limitation, we use less precise measurements and rely on slower biological mechanisms.
As of the time of writings this, the current design goal is to make a point and shoot model. low cost design distance, def of remote
Detecting Chlf over and area is complicated as plants grow, so does chlf because there is just more area

distance causes response to become weaker
optimize the detection range
Fluorescence is difficult to measure due to its low intensity. Because of this, wavelength optimization of both incoming and detection wavelengths is crucial. For most plants, fluorescence is at a maximum when hit with ~600nm and ~475nm light.
Fluorescence alone is also not a useful measurement, and many uses for it have been found experimentally using fluorescence ratios.
Current theory is that we are measuring between pulses, potentially related to response time.
