ABSTRACT:
A first and a second sensor array21and22arranged at the approximate image forming plane of a pair of optical systems, and a third sensor array23arranged at a spacing h from the first and second sensor arrays21and22. The image interval X is corrected to a standard image interval K=X (1−tan θ/tan(ψ+θ)) when the object image intersects the optical base length R0via the object image inclination ψ=tan−1(h/z) calculated from the image forming positions of the object images T1and T2detected by the sensor arrays21and22, and the dislocation angle θ formed by the sensor and the optical system detected after assembling the device.
