We adapt concepts from optical correlation and optical pattern recognition to propose a method for generating reconfigurable multiple spots with high efficiency. The generated spots correspond to the correlation spikes in optical pattern recognition. In pattern recognition, optimizing the correlation filter is constrained by the target pattern to be detected. The reverse process of light projection grants the freedom to optimize both the target pattern and the correlation filters. Combined with contemporary spatial light modulation technologies, the proposed method can yield dynamically reconfigurable optical patterns with high efficiency for optical micromanipulation and other applications.
