摘要：
An apparatus for motion compensation modeling of an eye parameter, comprising: means for illuminating a selected ocular surface (116-120) with at least one incident light beam and means for directing at least two light beams that return from the illuminated ocular surface to an imaging device (110)； a first measurement means (100) for measuring a plurality of eye position parameters with respect to an optical reference coordinate system of the apparatus wherein the plurality of position parameters include lateral displacement along an x axis of the optical reference coordinate system, the lateral displacement along a y-axis of the optical reference coordinate system and the axial displacement along a z-axis of the optical reference coordinate system； a second measurement means (200) for measuring an interference signal at a plurality of optical reference coordinates, wherein the measurement of the plurality of position parameters and the measurement of the interference signal are time synchronized； and means for correcting the interference signal to account for offsets of the plurality of position parameters； and means for modeling the eye parameter based, at least in part, on the corrected interference signal characterized in that the plurality of position parameters include cycling around the z-axis, rotation around the x-axis, and rotation around the x-axis Y.Un aparato para el modelado con compensación de movimiento de un parámetro de un ojo, que comprende: medios para iluminar una superficie ocular seleccionada (116-120) con al menos un haz de luz incidente y medios para dirigir al menos dos haces de luz que regresan de la superficie ocular iluminada a un dispositivo de formación de imágenes (110)； un primer medio de medición (100) para medir una pluralidad de parámetros de posición del ojo con respecto a un sistema de coordenadas de referencia óptica del aparato en el que la pluralidad de parámetros de posición incluye el desplazamiento lateral a lo largo de u
