    摘要： In a wavefront sensor, an optical wavefront to be measured is split into a first optical path and a second optical path. A wavefront W1 in the first optical path is transmitted through a first compensation member 7, and a wavefront W2 in the second optical path is transmitted through a second compensation member 8. Wavefronts W1 and W2 are mixed together by a semi-transparent mirror 6 with the wavefronts being displaced from each other by a shearing quantity S to form an interference fringe. An optical path difference that occurs between two wavefronts W1′ and W2′ which reach the interference measurement plane M in a state where the wavefronts are inclined due to the arrival direction of the optical wavefront to be measured is compensated when the wavefronts W1′ and W2′ are transmitted through the first and second optical path difference compensation members 7 and 8, respectively.

    摘要： In a wavefront sensor, an optical wavefront to be measured that has entered an entrance pupil P is split into a first optical path L1 and a second optical path L2 by a semi-transparent mirror 3. A wavefront W1 traveling in the first optical path L1 is transmitted through a first optical path difference compensation member 7, and a wavefront W2 traveling in the second optical path L2 is transmitted through a second optical path difference compensation member 8. The wavefronts W1 and W2 are mixed together again by a semi-transparent mirror 6 in a state where the wavefronts are displaced from each other by a shearing quantity S to form an interference fringe on an interference measurement plane M. The intensity distribution of the interference fringe is measured by a photodetector 9, and a configuration of the optical wavefront to be measured is measured by a wavefront measurement portion 10. An optical path difference that occurs between a wavefront W1′ and a wavefront W2′ which reach the interference measurement plane M in a state where the wavefronts are inclined due to the arrival direction of the optical wavefront to be measured is compensated in advance when the wavefronts W1′ and W2′ are transmitted through the first and second optical path difference compensation members 7 and 8, respectively.

    摘要： An optical reading apparatus and a multifunction-type image forming apparatus, with a minimized thickness in a cabinet height direction and a housing shaped along an upper shape of discharge tray of the image forming apparatus provided thereunder. The optical reading apparatus comprises: platen glass defined with one end and the other end, on an upper surface of which an original document is placed; an optical reading unit that translates between the both ends on a lower surface of the platen glass, for obtaining image data by irradiating an original document surface with light through the platen glass; a control circuit board connected to the optical reading unit, for processing an electric signal; and a housing wherein a side on the side of the other end is thicker than a side on the side of the one end. The image forming apparatus has a cabinet containing: sheet discharge unit for discharging an image formation sheet from a lower-part lower-side on the thicker side of the housing of the optical reading apparatus toward a lower-part upper side on the thinner side of the housing; and a discharge tray on which the image formation sheet discharged from the sheet discharge unit is received and stacked.
