摘要:The fringe projection technology is widely used in 3D measurement fields. However when the technology is applying to translucent objects, the subsurface scattering and absorbing always leads to a decline of the measurement accuracy. The aim of this paper is to propose a dual-dire...

摘要:We investigate the optical interference theory of double elliptically polarized beam (EPB) by using complex electric field amplitude vectors, compared with the real vectors for linearly polarized beam (LPB). Numerical simulations can show the differences between them quantitative...

摘要:We discovered that a helical surface relief can be created in azo-polymer film merely by the irradiation of circularly-polarizedlight without any orbital angular momentum. The chirality of the surface relief was also determined by thehandedness of the circular polarized light.

摘要:Microhole collapse property of polarization maintaining photonic crystal fibers (PM-PCF) and its effect on the splice loss and polarization cross-coupling during fusion splicing were investigated. The relationship between the microhole collapse and polarization cross-coupling are...

摘要:We propose three-wavelength phase-shifting interferometry selectively extracting wavelength information from wavelength-multiplexed images with arbitrary phase shifts. Wavelength information is multiplexed on the space and spatial frequency domains and is separated in the polar c...

摘要:A laser diode temperature control scheme is adopted to achieve the laser wavelength tuning of a narrow linewidth laser, which sends commands by serial communication to change the laser diode temperature. The laser diode temperature is presented by the temperature sensitive resist...

摘要:Human retina is different from other ocular tissues, such as cornea, crystalline lens and vitreous because of high scattering performance. As an anisotropic tissue, we cannot neglect its impact on the polarization state of the scattered light. In this paper, Mie scattering a...

摘要:Micro satellites have been widely used in the target monitoring and tracking. Aimed to reduce the ground operator's workload, a target location method based on homography and scene matching is proposed in this paper. For the first time satellite flies over target area, it needs t...

摘要:Visibility data have long needed to traffic meteorological monitoring and warning system, but visibility data have monitored with expensive special equipment. Visibility degradation in fog is due to the light scattering of fog droplets, which are transit from aerosols via ac...

摘要:Decoding of information in the brain requires the imaging of large neuronal networks using e.g. two-photon microscopy (TPM). Fast control of the focus in 3D can be achieved with phase shaping of the light beam using acoustooptic deflectors (AODs). However, beam shaping using AODs...
