Background:

Dynamic projection mapping is essential for adapting projections to moving objects.
Microscopy requires similar dynamic projection for stimulating photosensitive cells in motion.

Purpose of the Study:

To propose a novel projection method for microscopy with millisecond latency.
To enable dynamic projection mapping for optogenetic stimulation of moving cells.

Main Methods:

Utilized a low-latency digital micromirror device.
Integrated a high-speed vision system for real-time tracking.
Developed a system for dynamic light projection responding to object movement and deformation.

Main Results:

Achieved a photon-to-photon latency of 6.56 ± 1.76 ms.
Successfully demonstrated dynamic projection mapping on a randomly moving target.
Enabled precise light projection for stimulating moving cells.

Conclusions:

The developed system provides millisecond-latency projection for microscopy.
This technique is suitable for dynamic optogenetic stimulation of moving or deforming biological samples.
Advances dynamic projection mapping applications in live-cell imaging and manipulation.
