偏振光束由于其应用广泛并且具有某些特殊的性质,被引起广泛的关注。因此,如何通过实验的方法产生偏振光束在实际应用中是非常必要的。现提出了一种产生非相干柱对称偏振光束的方法,用偏振膜做成的圆锥偏振装置是产生非相干柱对称偏振光束的关键部件,装置能够将入射的一束自然光经透射后直接转变为非相干柱对称偏振光束。实验结果表明,该方法简单有效,所产生的非相干柱对称偏振光束可靠性好、实用性强。

Polarized beam has attracted much attention recently due to its novel properties and applications. Experimental method of special polarized beam is very significant and necessary. A simple and convenient method for generating cylindrical symmetry incoherent vector beam is proposed. Conic polarization device which is made of polarizing film is core component in this method. Incident beam can be converted into cylindrical symmetry incoherent vector beam when passing through this device. Experimental results show that this kind of method is simple and feasible. The cylindrical symmetry incoherent vector beam has features of high reliability and good applicability.
