Abstract

Multispots in three-dimensions generated by phase mode spatial light modulators (SLMs) are very useful in laser processing or light induced biological treatments, such as optogenetics. So far, the intensity of the focus spots varies depending to the distance from optical axis. In order to equalize intensities in all generated spots, simple feedback method was applied. Further, look up table was created by dividing imaging area in sectors. Experiment results show improvement in the random spots at some degree, however, further analyzation is required.
