Electro-Optical Imaging Technology Based on Microlens Array and Fiber Interferometer

Abstract

To reduce the volume and weight of traditional optical telescopes effectively, this article proposes an electro-optical imaging technology based on a microlens array and fiber interferometer. Pairs of microlenses in the microlens array collect light and couple it into a fiber interferometer to form interference fringes. Then the amplitude and phase of a large number of interferometer baselines are analyzed to generate images. In this work, the principle of electro-optical imaging technology has been analyzed according to the partially coherent light theory. The microlens-array arrangement method and baseline pairing method have been optimized for arbitrary targets. From the simulation results, it was found that the imaging resolution depends on the maximum baseline length, and the imaging quality could be effectively improved by adjusting the Nyquist sampling density and baseline pairing method. This technology can provide an important reference for the miniaturization and complanation of imaging systems.

“…The technology of the microsystem component manufacturing process is usually used in advanced scientific technology industries such as microsystems, opto-mechatronics, biomedicine, display monitors, opto-electrics, optics, and information communication. Microsystem components are usually used as the key to enhancing product efficacy and bringing scientific products into reality, for example, in the array grating, phased-array lens, diffusion membrane, and light guide plate of the backlighting modules of LCD monitors; the microchannel structure used for examining diabetes or cancers in biomedical engineering [1][2][3]; and the micro-lens structure [4][5][6][7][8][9][10][11][12] for capturing images in the 3C industry. Optical waveguide components have been applied in microsystems to transmit optical signals.…”

Structure Design and Image Reconstruction of Hexagonal-Array Photonics Integrated Interference Imaging System

“…To overcome the lack of zero frequency, Yu et al proposed a "checkerboard" design and an aperture matching method, which can acquire a uniform frequency distribution together with the zero frequency [8]. Recently, Yang et al proposed a complex rectangular sub-aperture arrangement method to improve the imaging resolution further [9]. Rectangular patterns realize the dense arrangement of micro-lens, which greatly increase the number of sampling points compared with the radial patterns.…”
