“…In order to reduce the limitations of environmental temperature on DOE applications, the design goal is to achieve polychromatic integrated diffraction efficiency [53], which can improve the imaging quality of the imaging system. Mao et al [54][55][56][57] not only considered the wavelength range, but also considered the effects of incident angle and temperature on diffraction efficiency when designing MLDOE. This design improved the diffraction efficiency of MLDOE in wide wavelength, large angle, and wide temperature ranges, which is of great significance for the optimization design of practical hybrid imaging optical systems.…”

Diffractive optical element (DOE) has the characteristics of lightweight, flexibility, and easy replication, which meet the needs of miniaturization, integration, and mass production of optical systems. They play and will continue to play an important role in multiple fields of modern optics. In application scenarios with different requirements, researchers need to flexibly apply design methods to customize DOE with specific functions. On the basis of reviewing the basic principles of DOE design, existing DOE design methods based on diffraction principle and interference principle are briefly described. Combined with the latest application progress of DOE in the field of imaging and display, the applicability of DOE design methods is elaborated. Finally, the difficulties faced in DOE design are summarized, and potential application directions in future technology are prospected.

Growing interest in free-space optical communication, due to the high bandwidth and security provided by these links, has generated the necessity of designing high-performance satellite terminals. In order to develop these terminals, the optothermo-mechanical phenomena that appear in the space environment and their effect on optical communication links have to be understood in detail. A review of the opto-thermo-mechanical phenomena occurring in spaceborne terminals is presented, describing the relevance of each of them. The methods found to compute the impact on the communication performance due to opto-thermo-mechanical phenomena are collected by building the bridge between the optical and communication performance parameters. Finally, techniques available to mitigate the detrimental effects of these phenomena are classified, and the relevant research challenges are identified.
