Fourier plane detection scheme is commonly used in optical tweezers’ detection system. We have recently shown that for axial movements of the bead, the back focal plane (BFP) intensity pattern contains two anti-correlated areas where collecting signal from both areas with degrade the quality of the positional signal. We have shown that collecting signal from either of the areas would benefit from either better sensitivity or wider linear detection range. We have also shown that there is no very sharp border between mentioned areas.
