Calibration(of different units of intensity) for Tmaze and Joystick platform

  1. For the Joystick experiment – We continuously varied the light intensity at the tip of the optical fibre and measured it using the Lux meter at first and then in mW/cm^2. Then both these readings were taken down and the best fit was generated which depicted the measured fit. Now a theoretical fit was also generated and plotted. This is given below
  2. We also did the best fit for the Tmaze experimental setup. We measured the light intensity on both sides of the chamber in between and took the average of it. 
  3. The Information for plotting the theoretical fit was obtained from here: https://www.dfisica.ubi.pt/~hgil/Fotometria/HandBook/ch07.html

    ## 1 Watt = 517.031 lm at 590 nm

    ## 1 lux = 1 lm/m2

    ## Therefore: 517.031 lux = 517.031 lm/m2 = 1 Watt/m2 = 1000mW/mm2 = 10mW/cm2
