Density fluctuations in the LT-4 tokamak plasma are investigated using a Phase
Scintillation Interferometer operating at 10.6/Ltm which is sensitive to density fluctuations
of δnₑ/nₑ> 10⁻¹⁴. The plasma is imaged across a linear detector array
which can be rotated to record projections in any direction, from toroidal to poloidal. The theory of forward scattering from plasmas is developed from the Rytov
approximation and aspects of the Fourier diffraction projection theorem relevant
