We present the preliminary results from our HST/NICMOS imaging polarimetry on optically thin PPNs. The data show the dust distribution in an unprecedented detail. The structure of these faint PPNs is revealed via polarization properties of the dust-scattered light without much interference from the bright central star, proving the unique advantages of the technique over simple imaging.
