Zusammenfassung:The invention discloses an ultra-high-speed optical parametric amplification optical imaging system which comprises a light source system, a light splitting delay system, an optical parametric amplification system and an image recording system. Beam splitting and delay processing are carried out on incident continuous or long pulse laser; a plurality of sub-beams carrying object information with specific time delay are obtianed; the incident ultrashort pulse laser is taken as a pump, non-collinear optical parametric amplification is carried out on the sub-beams to obtain an idler frequency light array carrying object information with specific time delay, and imaging an image of the object information with the specific time delay carried by the incident idler frequency light array; imagingof an object at different moments is realized, framing imaging with high spatial bandwidth product, high framing frequency and more than ten frames is realized, and ultra-high-speed optical imaging with picosecond and even fe
