In this study, we design and present a five-fold digital slit-lamp microscope (DSLM) with built-in photographic lens and CCD. The initial structures of the front objective, Galilean telescope system, and photographic lens are systematically investigated and discussed in the design. A progressive optimization process is employed in the non-coaxial system design after the coaxial system achieves high performance. The analysis of spot diagrams and the modulation transfer function (MTF) show that this DSLM optical system achieves quasi-diffraction-limited performance and enables high-quality imaging for ophthalmic examination. Furthermore, tolerance analysis of this optical system is also performed, which provides a theoretical basis for machining and assembly. This design provides an idea for the design of a digital-zoom microscope in biomedical imaging instruments.

In this work, methods and procedures are investigated for the holistic simulation of the dynamicalthermal behavior of high-performance optics like lithography objectives. Flexible multibody systems in combination with model order reduction methods, finite element thermal analysis and optical system analyses are used for transient simulations of the dynamical-thermal behavior of optical systems at low computational cost.

Large Satellite

There is a great demand in space and earth observations applications. Traditional satellite missions have complex design architecture involving high cost in design, operation, launch and maintenance. Thus single large satellite is replaced by multiple, small satellites with distributed network, collaboratively performing the same functionality of large satellite. This has been motivated researchers to explore the application of terrestrial Wireless Sensor Network (WSN) to space. The main objective of using space based WSN is to have full power of remote sensing capabilities at all the relevant time horizons and geographical scales with high performance and low cost. It also strives for an optimal solution that gratifies the standards, sizes, air interfaces, network architecture, access schemes, fault tolerance, operating system, hardware components of on-board diagnostics etc. This chapter discusses the characteristics and challenges of Space-Based Wireless Sensor Network (SWSN).
