The discussion revolves around the effects of noise on light signals, particularly in the context of optical amplification. Participants explore various types of noise that can influence light signals, including environmental factors and inherent sensor noise.
Participants generally agree that noise can affect light signals, but there is no consensus on the specific types of noise or their implications in different contexts. The discussion remains open-ended regarding the best approaches to learning photonics.
Participants mention various sources of noise without fully resolving how these factors interact or their specific impacts on optical amplification. The discussion includes personal experiences and suggestions for learning without definitive conclusions.
This discussion may be useful for students and professionals interested in photonics, optical engineering, or the effects of noise on signal processing in light-based technologies.
Drakkith said:Absolutely. The types of noise depend on the conditions you have. If you have a light source where you are also getting a lot of "light pollution", IE unwanted light from other sources, that will be noise. The sensor itself will have noise during readout as well. Even without these you will have noise thanks to the random nature of when photons are emitted and received.
zakee.fancy said:thanks for the reply..do u have an idea how to start learning photonics..i m interested in this field but there are far too many concepts too master..i have done my undergrad in electronics and I am starting as a master's student in photonics.it wud be great if you can give me some idea where from where to start.I know basic electromagnetics but there is still too much too learn..hope to hear from you soon.
