Effect of Amplifier Gain on Photoacoustic SNR (Signal to Noise Ratio) in an LED-based Photoacoustic Imaging System
Laser Ther. 2020 Jul 17;29(1):77-85. doi: 10.5978/islsm.20-OR-09. Epub 2020 Nov 18.ABSTRACTThe possibility of using photoacoustic imaging for functional diagnosis has attracted much attention especially in the clinical field. Among such imaging systems, a system, which offers real-time imaging using compact and low-priced LEDs as a light source, has appeared. Compared to solid state lasers, the LED pulse energy was extremely small, so it had been thought that imaging would be extremely difficult, but by adding a pre-amplifier, real time photoacoustic imaging became possible. However the signal-to-noise ratio (SNR) and the ...
