Based on the principle of space-time duality, time lens can be used for reference in theoretical research and practical application. As an optical device, the advantages of time lens lie in its simple structure and diversified functions. So far, the time lens has realized the functions of broadening, compressing, Fourier transform and time reversal of optical signal waveforms. In this paper, the time reversal function of the time lens imaging system is used to realize the effect of the optical logic "NOT" gate, which greatly simplifies the logical "NOT" operation system and greatly improves the operation speed. The research on the use of the optical logic "NOT" gate as Manchester code signal generator is also carried out.
