We present a method of rendering aerial and volumetric graphics using
femtosecond lasers. A high-intensity laser excites a physical matter to
emit light at an arbitrary 3D position. Popular applications can then be
explored especially since plasma induced by a femtosecond laser is
safer than that generated by a nanosecond laser. There are two methods
of rendering graphics with a femtosecond laser in air: Producing
holograms using spatial light modulation technology, and scanning of a
laser beam by a galvano mirror. The holograms and workspace of the
system proposed here occupy a volume of up to 1 cm^3; however, this size
is scalable depending on the optical devices and their setup. This
paper provides details of the principles, system setup, and experimental
evaluation, and discussions on scalability, design space, and
applications of this system.
