Note that in OMP100M, all of the sinusoids exactly lie on the grid points.
Their drawback is that it is difficult to guarantee that the selected laser points exactly lie on the calibration target boundary.
Due to measurement errors, the 3D space points X o,l, o=1,…,N might not exactly lie on a perfect circle in the plane Π l.
However, the actual targets may not exactly lie on the grid points no matter how densely the parameter is grided, which introduces mismatch between the predefined dictionary and the actual one.
The off-grid problem usually emerges because we do not often have enough priori knowledge to generate a perfect grid to guarantee that all of the signals exactly lie on grid points.
"They didn't exactly lay it on a plate for me in 2010, did they?" Now what?
He didn't exactly lay it all on the line with that vote.
Well, he didn't exactly lie.
