“…The electro-optical modulation of this band is a way of external modulation that achieves more easily and the laser parameters are modulated by the electro-optic effect by using electro-optical crystal materials and under the action of external electric field [2]. The electro-optic modulator with output power of 250mW, rate of 500Mbps can meet the needs of space optical communications from 8 to 10 km.…”

Abstract� The beam energy is one of the important factors that affect space optical communications. The beam energy has a direct effect on communication link distance, detector SNR, communication BER and other parameters. To test and verify the related technologies in the space optical communications, the paper proposes a near-earth demonstration and verification experiment systems of emission and detection to the near-space optical communications, which have wavelength of 8tOnm-band, optical output power of 250mW, modulation ratio of 500Mbps, and achieve to link distance of 8-10 km and communication BER better than 10-8; analyzes the effect of collimator, electro-optic modulators and optical antenna elements on the beam power loss, beam diameter, divergence angle and other parameters in the system. Theoretical analysis and experimental results are basically consistent; the conclusions have great value on further research of the near-space and deep-space optical communications.

Dynamic coded x-ray tomosynthesis (CXT) uses a set of encoded x-ray sources to interrogate objects lying on a moving conveyor mechanism. The object is reconstructed from the encoded measurements received by the uniform linear array detectors. We propose a multi-objective optimization (MO) method for structured illuminations to balance the reconstruction quality and radiation dose in a dynamic CXT system. The MO framework is established based on a dynamic sensing geometry with binary coding masks. The Strength Pareto Evolutionary Algorithm 2 is used to solve the MO problem by jointly optimizing the coding masks, locations of x-ray sources, and exposure moments. Computational experiments are implemented to assess the proposed MO method. They show that the proposed strategy can obtain a set of Pareto optimal solutions with different levels of radiation dose and better reconstruction quality than the initial setting.
