New Ultrafast Photography by Ordinary Optical Devices: Compressed Ultrafast Spectral-Temporal (CUST) Photography
Dr. Lidai WANG of CityU and Professor CHEN Feng of Xi'an Jiaotong University have jointly developed the novel compressed ultrafast spectral-temporal (CUST) photography, which is a new imaging technique that can simultaneously achieve high frame rate, high frame number and high spectral resolution, and can offer an important tool for observing complex transient processes on the femtosecond (10-15second) timescale. It can also overcome the existing limitations in imaging speed, frame number and spectral resolution.
According to Dr. Wang, CUST is based on the principle of spectral-temporal coupling of femtosecond laser pulses. However, such ultrafast imaging system can be built with ordinary optical devices, therefore this technology can be widely used in an easier and much cheaper way, and can be commonly applied in research institutes. This study also enables researchers to acquire images of femtoseconds over a long period of time with a wide spectrum, and will facilitate the research of ultrafast processes in a wide range of applications in physics, chemistry and biology.
