FIELD: physics.
SUBSTANCE: apparatus has several sensitive elements and at least a second optoelectronic sensor lying in a plane inclined relative the plane containing a first sensor and relative the optical axis of the image forming apparatus, and which scans the same zone as the first sensor, as well as a device for calculating optical aberrations affecting each sensitive element of two sensors. That inclined plane has a line which connects two sensors and lies in the plane containing the first sensor.
EFFECT: design of an apparatus for measuring defects of an image forming apparatus with a sensor which is accurate, easy to make and use and cheap.
