Compressive sampling and gated viewing three-dimensional laser radar

By a new framework named compressed sensing (CS) for the compressive sampling achieving simultaneous sampling and compression of signals, it is possible for us to perform laser imaging using a single detector rather than focal plane arrays having millions of pixels. Moreover, based on acquiring a serial of time-slicing images through combining compressive sampling with gated viewing, the three-dimensional(3D) scene can be reconstructed, wherein a single-pixel gated viewing 3D imaging LADAR system prototype is proposed in this paper; numerical experiments using the proposed 3D image formation model evaluate the system preliminarily and draw the main result that higher range accuracy for 3D scene as the increase of pseudorandom projections by qualitative analysis from Lissajous figures.
