  In this paper, a method for increasing the temporal resolution of a temporal
imaging system has been developed. Analogously to the conventional spatial
imaging systems in which resolution limit is due to the finite aperture of the
lens, in a temporal imaging system, finite temporal aperture of the time lens
is responsible for limited temporal resolution. Based on the method used in
spatial structured illumination super-resolution microscopy in spatial optics,
we have utilized time prisms, which are temporal versions of conventional
prisms, to shift the illusive frequency components of the input signal to
become captured by the time lens. This method would pave the way to a
high-resolution temporal imaging system which has applications in the
observation and study of fast and rare phenomena such as dynamics and evolution
of optical rogue waves or cancer cells in the blood.
