Title: Image reader and shading correction method for the image reader
Inventor: MATSUMOTO HIDEO
IPC: H04N1/401
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To improve the processing efficiency by driving a white reference roller with a white reference face opposite to a read face of a contact sensor in an original carrying direction and applying shading correction to data outputted from a read means attended with the drive so as to facilitate removal of dirt deposited on a surface of the roller.

Title: Method and instrument for measuring double refraction
Inventor: MIURA AKIHISA
IPC: G01N21/23
Filed: 1988-08-11
Abstract: PURPOSE:To derive the double refraction of a plate-like member by placing the plate- like member between a pair of polarizing plates whose polarization directions are intersected orthogonally with each other, and also, whose surfaces are parallel to each other and measuring the light quantity of a light beam for transmitting through a pair of polarizing plates. CONSTITUTION:An incident light 7 from a light source 1 passes through a slit part 6 and is made incident on a polarizing plate 2 having the polarization direction in the prescribed direction and transmits through it. A slit-like light beam which transmits the polarizing plate 2 becomes a linearly polarized light, is made incident on a plate- like member 4 and transmits through it, and when there is a double refraction in the plate-like member 4, the light becomes an elliptically polarized light. A polarized light component which vibrates in the direction vertical to the polarization direction of the polarizing plate 2 of this elliptically polarized light corresponds to magnitude of the double refraction of the plate-like member 4. The elliptically polarized light is made incident on a polarizing plate 3, and passes through it. As for the slit-like light which passes through the polarizing plate 3, its light quantity is condensed and measured by a light receiving part 5. When there is no double refraction, the light quantity condensed by the light receiving part 5 becomes zero.
