This paper presents a thorough review of optical voltage sensors (OVS) based on Pockels effect which contain many design schemes over the last decades. The principle and optical circuit of each scheme are described respectively, such as Integrated-optic Pockels cell, multi-segment OVS, quasi-reciprocal reflective OVS, dual-crystal OVS and OVS with special optical fiber. The main strengths and weaknesses in every scheme are analyzed. Finally, we summarized the remaining problems in OVS and the future research direction as well to improve the performance of OVS based on Pockels effect.

At present, traditional organic agents and catalyst have the lack of low efficiency, poor selectivity, toxicity, environmental pollution and so on. As a new type of green high efficient solvent and catalyst, deep eutectic solvents (DESs) have become one of the hotspots in the green chemistry field. In this paper, domestic and foreign research on DESs in separation and catalysis are reviewed in detail. Firstly, we summarize the characteristic properties of DESs. Secondly, the paper presents a review of DESs application in separation and catalysis. Thirdly, it point out the future research direction of DESs in separation and catalysis fields. All these provide comprehensive guidance in the future study and application of DESs.

Drawing on network and fiscal federalism theories, we investigated central government patronage and donor aid as antecedents of budget performance in local government (LG). A mixed methods design with data collected from 18 LGs, two ministries, and four donor agencies in Uganda was employed. Results revealed that both central government patronage and donor aid predict budget performance. Moreover, autonomy does not mediate the interactions as initially hypothesized. Implications for theory and practice are discussed and future research direction is provided.

Background: In machine vision, the 3D reconstruction is widely used in medical system, autonomous navigation, aviation and remote sensing measurement, industrial automation and other fields, and the demand for reconstruction precision is significantly highlighted. Therefore, the 3D reconstruction is of great research value and will be an important research direction in the future. Objective: By reviewing the latest development and patent of 3D reconstruction, this paper provides references to researchers in related fields. Methods: Machine vision-based 3D reconstruction patents and literatures were analyzed from the aspects of the algorithm, innovation and application. Among them, there are more than 30 patents and nearly 30 literatures in the past ten years. Results: Researches on machine vision-based 3D reconstruction in recent 10 years are reviewed, and the typical characteristics were concluded. The main problems in its development were analyzed, the development trend was foreseen, and the current and future research on the productions and patents related to machine vision-based 3D reconstruction is discussed. Conclusion: The reconstruction result of binocular vision and multi-vision is better than monocular vision in most cases. Current researches of 3D reconstruction focus on robot vision navigation, intelligent vehicle environment sensing system and virtual reality. The aspects that need to be improved in the future include: improving robustness, reducing computational complexity, and reducing operating equipment requirements, and so on. Furthermore, more patents on machine vision-based 3D reconstruction also should be invented.
