“The filtering capacities of the lateral line system of the tail could improve the signal-to-noise ratio, avoiding overstimulation of the canal neuromasts.”

This research was made possible thanks to the A3COSMOS and A3GOODSS archival projects, which enabled researchers to gather a large number of galaxies observed with a high enough signal-to-noise ratio for detailed analysis.

The team's pioneering approach also integrates broadband, high-frequency modulation of the OPO output, which allows the enhancement of the signal-to-noise ratio, providing even greater detection precision.

They analyzed two commonly used image processing metrics: the peak signal-to-noise ratio and the structural similarity index.

This higher voltage enabled their device to more than double the signal-to-noise ratio.
