a method of rotation-photograph was suggested by which the kinoform with axial rotating symmetry was made up, and experimental results of the spherical kinoform was presented.
本文提出了用旋转照相法设计制作旋转轴对称相息图的方案,并给出了球面相息图的实验结果。
a way to manufacture kinoform of actual object is proposed. a kinoform is given by two steps—inputting optical hologram in computer by scanning and then analyzing its information of object wave.
the method reduces the noise caused by discrete phase on reconstructing imago. this method can apply to either spherical or aspherical kind of kinoform with axial rotating symmetry.
此方法减小了相位离散值引起的量子化噪音,它适用于制作一切球面和非球面的具有旋转轴对称的相息图。
a kinoform with the characters of two-channel was fabricated by adding quadratic phase factors into conjugate frequency spectrum of object.
通过对物的频谱加入二次相位因子,使其具有双通道的特性;
both phase values associated with each kinoform cell and coordinates of transition points can be used as variables of merit function in optimization procedure of the mpk.
