Ultrafast imaging is presently attracting immense research interesting on the global level due to its powerful ability for studying space-time dynamics in photonic materials, 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 and spatial resolution. 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 eigen spatial resolution than 30 line pairs per millimeter, which has no intrinsic limitations of imaging speed from outside but only limitations due to optical devices such as laser and non-linear crystal film. Furthermore, its spatial resolution is high enough, which can make it possible and significative to study and further analyze the details of targeted object on the level.
