Influence of Optical Fiber Parameters on the Speckle Pattern and Spectral Observation in Astronomy

Optical fibers serve as a bridge to transmit starlight into the spectrograph in fiber spectral surveys. Due to the interference between multiple modes supported within the fiber, a granular speckle pattern appears on the end of the fiber and leads to an uneven and random energy distribution in the s...
