I am currently in university and have been assigned a project where i have to build a sensor. To narrow and simplify the question down, i basically have to measure the light emitted from an optical fibre using a photo diode or a photo transistor. As i don't have a very good basic knowledge in electric circuits can anyone tell me how i would connect a voltmeter or something to measure the change in light intensity received by the photo diode or phototransistor? Is all i need just the actual photodiode or photo transistor and the voltmeter or do i need any other extra components?
Also, if i cut off the fibre optics from a fibre optic lamp, will they still be able to work, i.e. i will still be able to use them to transmit light and receive light?
