Abstract: System and method for sensor alignment. In one example, a reimaging optical system includes reimaging foreoptics positioned to receive and reimage incident electromagnetic radiation to produce an intermediate image plane and output an optical beam of the received incident electromagnetic radiation, an imaging optical apparatus positioned to receive the optical beam and focus the electromagnetic radiation of the optical beam onto a first focal plane, a first imaging sensor positioned at the first focal plane and configured to produce a first image responsive to receiving the electromagnetic radiation of the optical beam, an alignment object selectively positioned at the intermediate image plane and configured to superimpose an alignment tool upon the first image, and a controller coupled to the first imaging sensor and configured to perform an alignment process for the first imaging sensor based on at least a position of the alignment tool in the first image.

Abstract: A method for determining positions of moving targets in unbiased three-dimensional (3D) measurement spaces using data collected against the moving targets by an electro-optical or infrared (EO/IR) sensor, the method comprising receiving data collected from electrical signals reflected from the moving targets in a first focal plane of the EO/IR sensor at a first time point, receiving data collected from electrical signals reflected from the moving targets in a second focal plane of the EO/IR sensor at a second time point, generating two-dimensional (2D) measurement data for the moving targets in the first and second focal planes, calculating 3D target velocities for the moving targets using the 2D measurement data, and estimating local 3D positions within a first unbiased 3D measurement space for the moving targets at the first and second time points based on the 3D target velocity.
