abstract = {In this paper, we show a proof-of-concept method to parallelise 

 phonon microscopy measurements for cell elasticity imaging by 

 demonstrating a 3-fold increase in acquisition speed which is 

 limited by current acquisition hardware. Phonon microscopy is 

 based on time-resolved Brillouin scattering, which uses a 

 pump-probe method with asynchronous optical sampling (ASOPS) to 

 generate and detect coherent phonons. This enables access to the 

 cell elasticity via the Brillouin frequency with sub-optical 

 axial resolution. Although systems based on ASOPS are typically 

 faster compared to the ones built with a mechanical delay line, 

 they are still very slow to study real time changes at the 

 cellular level. Additionally, the biocompatibility is reduced 

 due to long light exposure and scanning time. Using a multi-core 

 fibre bundle rather than a single channel for detection, we 

 acquire 6 channels simultaneously allowing us to speed-up 

 measurements, and open a way to scale-up this method.},
