Research on Photonic Integrated Interferometric Imaging Mechanism and Space Spectrum Coverage
Photonic integrated interferometric imaging system has the imaging characteristics of small-scale, low weight, low power consumption, and high resolution, which is expected to replace the traditional large aperture telescopes to realize remote detection. The principle of optical interferometry imaging is studied, and the restoration model of space object interferometric imaging is established. The influence of microlens array arrangement on imaging quality is studied, and the design method of microlens array is proposed. The effect of optical coherent baseline matching on spatial target spectrum coverage is studied, the coherent baseline matching method that can cover high, medium, and low spectrum coverage efficiently is presented. Finally, effects of target image simulation restoration under different microlens array arrangements and interference baseline matching approaches are compared. The results show that the proposed arrangement of microlens array and interference baseline matching method can improve the spectrum coverage of space target and improve the restoration quality of target images.
