This paper deals with the parallel and independent translation of microscopic objects in three-dimensional traps by switching individual sources of a vertical-cavity surface-emitting laser (VCSEL) array on and off. Difficult calculations for dynamic manipulation are avoidable because light distributions are controlled in real time by direct modulation of the VCSELs. We constructed an experimental system in which target objects were irradiated from below with a one-dimensional VCSEL array. Experimental results demonstrated that two microscopic particles were trapped in three dimensions simultaneously, and then translated independently with a sequence of light distributions. The lower limit of intervals between times of changes of emitting VCSELs for translation was measured as 200 ms with 2 mW for each beam.
