Would it be possible to suspend these kinds of particles using a standing wave of ultrasound ? Perhaps something similar to https://www.researchgate.net/publication/265401333_Cell_and_Particle_Manipulation_in_an_ultrasound_standing_wave_trap https://www.researchgate.net/publication/265401333_Cell_and_... and then project the laser on them.
- andars 9y agoSorry, I'm not qualified to give a good answer. I would guess that the relatively long wavelength of ultrasound could potentially cause resolution issues.
- kakarot 9y agoNot only resolution issues, but accuracy issues as well. I doubt ultrasound can provide the same fidelity as a highly-tuned laser high-frequency laser beam when it comes to keeping something in one place.
- klintcho 9y agoThanks for both your answers. Though I was also thinking perhaps you could just suspend the particles in mid-air, and use the movable prism in a laser projector to actually "render" the projection (thus not needing to move them at at a high frame rate or at all). However I guess, you probably do need to move the particles as well to be able to make it a 3D volumetric shape in space (seen from all angles etc).
