  Ultrafast imaging is a powerful tool for studying space-time dynamics in
photonic material, plasma physics, living cells, and neural activity. Pushing
the imaging speed to the quantum limit could reveal extraordinary scenes about
the questionable quantization of life and intelligence, or the wave-particle
duality of light. However, previous designs of ultrafast photography are
intrinsically limited by framing speed. Here, we introduce a new technique
based on a multiple non-collinear optical parametric amplifier principle
(MOPA), which readily push the frame rate into the area of ten trillion frames
per second with higher spatial resolution than 30 line pairs per millimeter.
The MOPA imaging is applied to record the femtosecond early evolution of
laser-induced plasma grating in air for the first time. Our approach avoids the
intrinsic limitations of previous methods, thus can be potentially optimized
for higher speed and resolution, opening the way of approaching quantum limits
to test the fundamentals.
