Too Long; Didn't Read

The paper investigates the optimization of optical interpolation and the hermitian self-adjoint product identity in NFFT matrices for equidistant and non-equidistant time-domain measurements. It explores complexities in equidistant time-domain measurements and presents a proof of identity, shedding light on critical aspects of scientific research.
