METHOD FOR MEASURING TILT OF IMAGING ELEMENT AND APPARATUS FOR MEASURING TILT OF IMAGING ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring imaging element, to measure the tilt of an imaging element accurately, and to provide a measuring device using the same.;SOLUTION: The tilt measurement method is provided for measuring the tilt of the imaging element 110 with respect to an imaging device 100 that includes a lens barrel 120 in which an optical system 130 with positive power is disposed, and the imaging element 110 on which an optical image of a subject is formed via a lens barrel 120. The method includes: disposing an auxiliary lens 240 on the optical axis of the lens barrel 100 so that the focal point of the optical system 130 defined by incident light from the imaging element 110 coincides with the focal point of an auxiliary lens 240 defined by incident light from a subject; and measuring to determine whether light reflected by the imaging element 110 has been displaced or not with respect to measurement light incident on the optical system 130 via the auxiliary lens 240.;COPYRIGHT: (C)2012,JPO&INPIT
