RT Journal Article T1 Incoherent spatial impulse response in variable-cross-section photoreceptors and frequency-domain analysis A1 Lakshminarayanan, Vasudevan A1 Calvo Padilla, María Luisa AB The spatial impulse response of a single variable-cross-section photoreceptor has been characterized assuming the incoming radiation to be an initial field propagating under confinement conditions inside the receptor. By application of Fourier analysis the total transfer function is determined. Both the outer and the inner segments are characterized as low-pass filters. The dependence of the transfer function on the modal parameter is analyzed.
