Beam steering accuracy in holographic optical tweezers
[ANGLÈS] The use of spatial light modulators (SLMs) to achieve dynamic control of optical tweezers is observed to provide subnanometer precision in single trap positioning. However, some features concerning the digitalized structure of SLMs cause a loss of precision in certain kinds of experiments....

| Resumo: | [ANGLÈS] The use of spatial light modulators (SLMs) to achieve dynamic control of optical tweezers is observed to provide subnanometer precision in single trap positioning. However, some features concerning the digitalized structure of SLMs cause a loss of precision in certain kinds of experiments. In this work, positioning accuracy of holographic optical tweezers (HOTs) is profoundly analysed in these cases, and a correction methodology is proposed in order to improve trap positioning. |
