Speech title: "Terahertz Spectroscopy and Imaging Technology: From Source to System"
Abstract:The vibration and rotation frequencies of some organic and bio molecules are located in terahertz region. Therefore, by using terahertz spectroscopy technology, the macro-organic material can be detected and identified. Furthermore, because of the good transmission and low photon energy, terahertz wave is also considered as an option for homeland security check. m-i-n diode based on intrinsic GaAs for terahertz emitter is fabricated by University of Shanghai for Science and Technology (USST), whose operation frequency can reach 4.2 THz. Furthermore, some terahertz functional devices are also developed, i.e., broadband high efficiency terahertz absorber, whose absorption can be more than 95% from 0.6-2.6 THz. Based on the above terahertz emitter and functional material, an fast scan and fiber based terahertz spectroscopy system is fabricated. The system can realize 0.1 s/spectrum scan for drug functional group identification and cancel cell detection. Moreover, an active terahertz imaging system for homeland security is also developed. The system is based on multi detectors and fast vibration scan mirror, which can realize a scan ~1.3 s/ person with the resolution about 1.5 cm.

Speech title: "Imaging and Metrology Using Scattered Light"
Abstract:Random scattering of light, which causes the opaqueness of paper, paint and biological tissue is an obstacle to imaging and focusing of light. Scattered laser light produces random interference patterns, known as speckle, that contain scrambled information pertaining to the environment of the scatterers, and that make imaging difficult. On the other hand, in some systems scattered light gives access to information that cannot be obtained through ballistic light. For example, scattering can increase the effective numerical aperture of an optical system and thereby improve the resolution. To be able to use this information the scattering should be carefully controlled and characterised. I will show several recent methods to use information to control and focus focus scattered light and to use scattered light to obtain relevant information and images.

Speech title: "Metasurface for Photonics Application in Demand"
Abstract:The functionalities of traditional optical component are mainly based on the phase accumulation through the propagation length, leading to a bulky optical component like lens and waveplate. Metasurfaces composed of two-dimensional (2D) artificial structures have attracted a huge number of interests due to their ability on controlling the optical properties including electromagnetic phase as well as amplitude at a subwavelength scale. They therefore pave a promising way for the development of flat optical devices and integrated optoelectronic systems. In this talk, important research topics for photonics applications based on metasurfaces will be performed and discussed. Examples of Beam deflection, muti-dimensional holographic imaging, versatile polarization generation and analysis, multi-functional and tunable metadevices, engineering non-radiating anapole mode in free space and achromatic metasurface devices will be shown.

Speech title: "Online monitoring and off-line inspection of pharmaceutical pellet coatings using optical coherence tomography and THz imaging"
Abstract:The terahertz (THz) region of the electromagnetic spectrum spans the frequency range between the mid-infrared and the microwave. Over the last decade or so, THz technology has advanced considerably with THz imaging instruments now commercially available. One of the distinct features of THz imaging is its 3D imaging capability, seeing not only the surface features but also the internal structures of a sample. On the other hand, in the near-infrared region optical coherence tomography (OCT) has also proven to be a non-invasive and cross-sectional imaging technique that permits, for example, 3D images with micrometre resolution to be obtained. In this talk, I will present our recent work on the development of an integrated THz and OCT online sensor for intelligent monitoring of high-value manufacturing and a novel OCT sensor for healthcare applications.

Abstract:Authors proposed a feature quantity type whole-space tabulation method (F-WSTM) as a camera calibration-free 3D shape measurement. 3D shape measurement using grating projection method is useful method for many fields. However, the method is not robust for vibrating of the measurement device. Especially, the optical positions of an imaging sensor and lenses are deformed easily owing to vibration. The F-WSTM overcomes these weak points. In this paper, the principle and the experimental result are shown.

Speech title: "Fourier ptychographic imaging"
Abstract:Fourier ptychography (FP) is a recently developed phase retrieval technique for wide-field, high-resolution imaging. This technique stitches together many variably illuminated, low-resolution measurements in the Fourier space to expand the frequency passband and recover the high-resolution complex sample image. Without involving any mechanical scanning, it facilitates gigapixel imaging in a simple and robust manner. In this talk, I will discuss the principle of the FP approach and its applications in microscopy, quantitative phase imaging, 3D holographic imaging, and macroscopic imaging. I will discuss how to extend the FP approach for other imaging settings. The FP innovation may provide new insights for the development of high-resolution, high-throughput imaging platforms using photon, X-ray, and electron.

Speech title: "Superfast Photomechanics Testing of Robotic Flapping Wings"
Abstract:The flapping flight study is important to a variety of fields including biology, aerospace engineering and robotics. Over the years, the flapping flight study has been enhanced with experimental tools such as high-speed 3D imaging with photogrammetry. However, dense full-field mechanics testing of flapping wings is not well-documented so far mainly because of the limited spatial resolutions of photogrammetry based methods. Conversely, the structured light method with defocused binary stripe illumination can perform superfast (e.g. several kHz) high-resolution 3D imaging, and thus has the potential for dense mechanics analysis. In this talk, I will present our preliminary testing with a robotic bird. Specifically, I will talk about: (1) our superfast 3D imaging method for the robotic bird; (2) our point tracking method with geodesic computation; and (3) our strain computational method based on Kirchhoff-Love shell theory.

Abstract:Fourier single-pixel imaging (FSI) is a recently proposed computational imaging technique which allows for producing high-quality images by using a detector without spatial resolution. FSI is a breakthrough for the field, as it well tackles the problems of low quality and low efficiency of single-pixel imaging. More recently, FSI has been extended to three-dimensional imaging, multi-modality imaging, dynamic imaging, and encrypted imaging. What¡¯s more, FSI has been demonstrated that it outperforms Hadamard single-pixel imaging in terms of efficiency. The recent progress of FSI adds the value of practical application of FSI. And FSI may find important applications where the pixelated detectors are unavailable.
