1. An optical measurement system for measuring an optical fiber sensor including multiple optical cores, the system comprising:
a tunable laser configured to sweep laser light over a measurement range of wavelengths;
an optical amplifier configured to amplify the swept laser light;
an optical network configured to provide the amplified swept laser light to the multiple optical cores, and to output optical signals comprising reflected light from the multiple optical cores;
detection circuitry configured to convert the optical signals into electrical signals associated with the multiple optical cores; and
control and data processing circuitry configured to:
cause the tunable laser to sweep the laser light over the measurement range of wavelengths, and
control a gain of the optical amplifier based on at least one characteristic selected from the group consisting of: a sweep direction, a sweep rate, and an instantaneous wavelength of the swept laser light.
