Abstract
Se describen las características de la rejilla de onda sinusoidal y su utilidad para construir estímulos más complejos, la función de transferencia de modulación o contraste (MTF) y la función de sensibilidad al contraste espacial (CSF) diferenciando entre la contribución del procesamiento neuronal y la del sistema óptico del ojo. Se estudia la relación entre la resolución espacial y la CSF, los canales de frecuencia espacial, el efecto del error refractivo, edad, luminancia y patología en la CSF.
The characteristics of the sine wave grating and its usefulness to construct more complex stimuli, the modulation or contrast transfer function (MTF) and the spatial contrast sensitivity function (CSF) are described. The contribution of neuronal processing and that of the eye's optical system to CSF is differentiated. The relationship between spatial resolution and CSF, spatial frequency channels, the effect of refractive error, age, luminance and pathology in CSF is studied.
