We present a novel design of two-dimensional (2D) angular-resolved spectrometer for full beam characterization ultrashort intense laser driven proton sources. A rotated 2D pinhole array was employed, as selective entrance before pair parallel permanent magnets, to sample the into discrete beamlets. The beamlets are subsequently dispersed without overlapping onto planar detector. Representative experimental result protons generated from femtosecond interaction with thin foil target is presented.
