Experimental Results


Our Project is split into three phases. The first phase was trials using a sheet of paper to confirm our code worked as planned. The second phase is for doing trials on a diffraction grating using an optical setup, in order to obtain results and graph them in real time. The third and final phase is to finally do trials using the Photonic Spectrometer Silicon on Insulator Chip. As of March 1st, we are currently still in the second phase of testing. 

1st Phase: Paper Tests

For the first phase, we decided to test our code using a printed image of a rainbow, shining light on it and seeing how the code would process the image. 

Above there can be seen some graphical results taken when the camera was pointed at specific areas. During this trial, the program would capture the image to a numpy array, and would then graph only the first row of the array. In the future, we hope to graph all rows at the same time, as well as three distinct channels for Red, Green and Blue.

2nd Phase: Diffraction Grating Tests


In the second Phase, we have moved our experimental setup into the National Research Council of Canada. Here, we are testing the code by capturing the light coming off of a traditional diffraction grating. Using a more traditional Lens and Mirror setup, we can better capture the light coming off the grating. 





Here our graph has changed, we have been able to separate the different colour channels and plot them on the same graph. We have also been able to graph in real-time, and the graph can change depending on where the camera is located. However, we are still only graphing one row of the image array. We hope to be able to normalize the sum of each row and graph that, which should give us an overall result for the wavelength intensity of the image.
