Abstract

Optical measurement mechanics is a technique studying structural behaviors by processing optical information. It is significant to measure time accurately in high-speed processes. Optical time codes can be used to represent and measure time. However, current time codes have limitations, which may affect accuracy and stability of time measurement. Herein, a high-speed time measurement system is demonstrated, including the system architecture and the data processing approach. A binary optical model is developed to enhance anti-noise capability and increase accuracy of time measurement. Variablecontrolled experiments are carried out and analyzed to verify the effectiveness of the proposed processing model. With the model, requirements of hardware system and operation are reduced. The accuracy of time measurement can be stabilized at microsecond level in the presence of noises. The proposed binary optical time measurement has wide application prospect. It may contribute to various fields in photogrammetry, photo-mechanics, communications, and measurements.
