We demonstrate power-based refractive index (RI) sensing using a polymer optical fiber (POF) crushed with a slotted screwdriver. This structure can be easily fabricated by simply pressing the end of a slotted screwdriver against part of the POF. Neither external heat sources, chemicals, nor ultrasonic transducers, which have been conventionally used, are necessary. The transmitted power has a l...
Optical diffraction tomography (ODT) provides label-free three-dimensional (3D) refractive index (RI) measurement of biological samples. However, due to the nature of the RI values of biological specimens, ODT has limited access to molecular specific information. Here, we present an optical setup combining ODT with three-channel 3D fluorescence microscopy, to enhance the molecular specificity o...
