Improvement of signal-to-noise ratio in photothermal microscopy by optimizing detection aperture

Optics Communications, 2017
Abstract We present a method for improving the signal-to-noise ratio in photothermal microscopy by optimizing the detection aperture in the spatially segmented balanced detection scheme. Experimental studies show a 1.44-fold improvement in the signal-to-noise ratio compared with the previous scheme.
