AdatasynchronousacquisitionschemeoflightfielduniformitymeasurementbasedonFPGAisproposed.Inthe measurement of the uniformity of large-area light field，the probe step scanning method needs to scan the large-area light field，soitisnecessarytocollectboththelightenergyvalueanditscoordinatevalueofthelightfield.Theenergyvalueand three-dimensionalcoordinatesofthelightfieldmeasurement pointsaresynchronouslycollectedbydesigning asynchronous acquisition circuit in this scheme，and the one-to-one correspondence of the data is ensured. So that the synchronous automaticacquisitionof thelightpulse energyandthree-dimensionalcoordinatesisrealized. By theconstructionof the test platform，thesynchronousacquisitionschemeoflightfielduniformitymeasurementistested.Theexperimentalresultsshow thatthesynchronousacquisitionschemeisfeasibleandpractical.
