Imaging of micro particles in micro-fluidic channels is one of the recent thrust areas in research as it provides more flexibility in setup and analysis compared to conventional microscopy. However, a probe based imaging scheme, with achievable high resolutions incorporating multimodal analysis is one of the challenges researchers have been facing. In this context, this paper illustrates a simple dual modality high resolution flexible probe imaging system for imaging applications in micro/optofluidic channels. The proposed system exhibits axial and lateral resolution of about 16 μm and 3.12 μm respectively. This proposed system also exhibits a modulation transfer function (MTF) of about 38.42 %. The performance of the system is validated by imaging micro particles in a microchannel and obtaining the fluorescent emission spectrum simultaneously.
