A researcher whose joint work tests <point spread function> measurements using <fluorescent beads>. A bead image represents the <convolution> of the object with the microscope response. Comparing different bead sizes helps determine when the particle is small enough to serve as a useful approximation to a point source.<Measurement of point-spread function (PSF) for confocal fluorescence microscopy by InCheon Song and others>[Abstract and §3.2: finite-size effects and bead comparisons]{ref}
