Homodyne image reconstruction is combined with an iterative decomposition of water and fat from MR signals obtained from a partial k-space signal acquisition in order to maximize the resolution of calculated water and fat images. The radial spring element passes at an axial distance from the stop edge into a circumferentially closed jacket sleeve an inner contour of which extends farther radially than the edge contour of the optical component. A plurality of delay sensing circuits having slightly overlapping operating ranges and different centers of operation are connected in parallel with respect to a an input clock signal, which is passed through the delay sensing circuits. This operation is followed by a second bias applying cycle, in which a program bias is applied to the second part of the page, while a program verify bias is applied to, and data is sensed from, the first part of the page. A contrasting surface finish formed on the front surface includes at least two visibly distinguishable shades, with one shade covering at least a portion of the front surface defined by the overall pattern, such that the overall pattern can be seen when the light source is turned off.
