Abstract:
We propose and demonstrate a simple off-axis scheme for particle field holography that utilizes the particle forward scattering by means of a Fourier transform lens for both recording and reconstruction. This technique has the advantages of both the low speckle noise offered by off-axis holography and the minimal laser power requirement characteristic of in-line illumination.
