Vehicular Daytime High-resolution Imaging System Based on Phase-diversity Technology
A bent Cassergrain focus was used to connect a daytime imaging system to a 1.2 m aperture vehicular telescope. The system employs a short-wavelength infrared waveband for precise tracking and corrects the global atmospheric wavefront tilt at the same time. Double-pass imaging is applied to the near-infrared waveband to produce the image, while the phase-diversity technique is used to restore the image resolution. The system can detect and correct objects with a magnitude 5 or less at an image resolution that is close to twice the diffraction limit. The observation time is 6 hours longer than that of the adaptive system.
