  Thanks to the high degree of adjustability, holographic tweezer array has
been proved to be the best choice to create arbitrary geometries atomic array.
In holographic tweezer array experiment, optical tweezer generated by spatial
light modulator (SLM) usually is used as static tweezer array. Due to the
alternating current(AC) stark shifts effect, intensity difference of traps will
cause different light shift. So, the optimization of intensity equalization is
very important in many-body system consist of single atoms. Here we report a
work on studying of intensity equalization algorithm. Through this algorithm,
the uniformity of tweezer can exceed 96% when the number of tweezer size is
bigger than 1000. Our analysis shows that further uniformity requires further
optimization of optical system. The realization of the intensity equalization
algorithm is of great significance to the many-body experiments based on single
atom array.
