A dragging device restricting one-way rotation of a spool of a fly reel. The catalyst systems employed in the processes herein. The portable hands free device is adapted to be connected to the portable electronic device. As a result, the power consumption of the DRAM is reduced and a high speed read operation can be implemented with a high degree of probability. By noting that reference phase functions \u03c61 and \u03c62 are obtained by solving an equation from each vibration component contained in an intensity distribution I, the reference phase functions \u03c61 and \u03c62 are calibrated concurrently with measurement of two-dimensional spatial distribution S0, S1, S2, and S3 of Stokes parameters.
