Light sensor are light sensitive proteins, which are able to perform specific actions based on light induction. They typically make use of photopigments , which are structurally changed or reduced as reaction to excitation by photons. Some light sensor can be activated and deactivated by light; others follow an exponential decay to a ground state after excitation. The rate constants for this reactions can be computed from the number of induction events. the number of photons causing such an event. | Light sensor are light sensitive proteins, which are able to perform specific actions based on light induction.

For the convenience of determining the light sensor reaction rate constants, We make the hypothesis that all of light sensing process are the first order reaction. Reaction rate constants [s-1] for our ODE model can be computed as integral over all events at all wavelengths, the integral of the product of the photoconversion cross section σλ times the photon flux Nλ; In our case approximated numerically. | For the convenience of determining the light sensor reaction rate constants, We make the hypothesis that all of light sensing process are the first order reaction.
