3. Hyperspectral Imaging and Optical Measurements
The research focus of the API optical detection technology lies in spectral detection, optical holography, interference measurement, and the design and study of shear imaging systems. We have successfully developed high-speed spectral acquisition devices, including single-point and array-based systems, enabling simultaneous acquisition of high-speed and high-spectral-resolution spectral images. Furthermore, our team possesses extensive expertise in spectral measurement, integrated optics, Fourier optics, and computational optics. This has led to the development of a range of powerful systems and devices, such as Raman spectroscopy detection systems, phase modulators, Fourier transform imaging spectrometers, and various non-destructive testing systems. Prototypes of these systems and devices are directly designed and characterized in our laboratory through meticulous measurements. The integration of optical, electronic, and computational components allows us to create cutting-edge optical detection systems and equipment, further advancing the field of optical measurement and imaging technology.
