Abstract
The invention belongs to the field of optical imaging resolution detection. A resolution plate meeting the national standard is made into a resolution ruler and an optical dynamic target at the infinite point is simulated through the transformation of a collimator tube with large field of vision and the drive of a linear motor so as to realize the detection of the resolution of an aerial camera simulating aerial work in a moving state. The system comprises the resolution ruler, the linear motor, a driving system, a moving guideway, a grating displacement feedback system, the collimator tube with large field of vision, and the like.
Description
The invention belongs to optical imagery resolution detection range, be by national standard resolving power test target (see figure 1) is made the resolution chi, change by the drive and the big visual field parallel light tube of linear electric motors again, simulate unlimited distance dynamic optical target, the detection of resolution under the motion state when realizing thus to the actual aloft work of aerial camera.
Present dynamic resolution of aerial camera detects can't realize the linear motion type measurement.Have only and realize detecting by the formula approximate simulation rectilinear motion target that rotatablely moves.This method and virtual condition error are bigger.
Native system comprises resolution chi (see figure 2), linear electric motors and drive system, motion guide rail and the pattern displacement feedback system that complies with the national standard requirements, parts (see figure 3)s such as the big visual field of focal length 1m (5 ° of field angle) dynamic resolution of aerial camera straight line parallel light pipe.
