The present invention discloses one kind of double micro polarizing free stereo imaging device and method. The device includes image plane, slit grating and double micro polaroid. The double micro polaroid sandwiches the slit grating, and the micro polaroid in the image plane side is between the image plane and the slit grating. The double micro polaroid consists of two adjacent lines of micro polarizing units, which are orthogonally arranged.

本发明公开了一种双微偏振式自由立体成像的装置及其方法，该装置包括图像面、狭缝光栅以及双微偏振片，其中双微偏振片是指上下两层微偏振片将狭缝光栅夹在中间，其中处于图像面一侧的微偏振片处于图像面与狭缝光栅之间；所述的微偏振片由相邻两列微偏振单元的透光轴方向相互垂直的微偏振单元周期性分布构成，即所谓"正交排列"；所述的狭缝光栅由等宽度的遮光条纹平行排列组成。

The block of wood is 3/4" square and around 3 inches long. I made a slit in the wood with my hacksaw (the blade cut was the same as the brass) to about half way down the wood. I drilled a 1/4" hole perpandicular to the slit at the top of the wood and one just lower of the blade slit to house the shaft.

该座木材是3 / 4 "广场及约3英寸长，我作出了狭缝，在木材与我hacksaw，大约一半的方式下来的木材，我钻了一个1 / 4 "孔perpandicular向狭缝在顶端的木材和一只是较低的叶片狭缝向内务轴。

首次研究指出：文献中对码尺依赖性问题的已有解释以码尺改变时单个分形岛的行为变化为出发点，这与小岛法从大量断面小岛的周长-面积关系得到其周线分维数的测量思想不符合。

Moreover, the electromagnetic flux density and meniscus height increase in the form of chequerboard with increasing of slit number. The numerical results can exactly illuminate some experimental phenomena, and enrich the theoretical foundation of soft-contact continuous casting technology. In practice, a softcontact mold with slit number of 16 or 24 is recommended, the suggested frequency is around 20kHz, and the slit width is about 1mm.
