We present a comprehensive study on the spatio temporal weak measurement of a chiral ultrafast optical pulse. We create a chiral vector wave packet by transmitting ultrashort laser pulse via a birefringent or magneto-optic medium. Employing time-resolved leakage radiation microscopy, we examine how the real and imaginary components of the weak value parameter (ε) influence pulse propagation over time. Our technique allows us to detect and categorize the temporal polarization fluctuation in a 75 fs pulse with an excellent repeatability. The achieved experimental results demonstrate a satisfactory consistency with the theoretical predictions.
