Coded aperture compressive temporal imaging (CACTI) enables the capture of complex dynamic scenes in a single exposure. In this Letter, we introduce a dual-optical-path (DoP) system with conjugate masks employing a single digital micromirror device (DMD) to simultaneously capture the original and complementary measurements to enhance the reconstruction quality. Our findings demonstrate that combining these measurements improves spatial resolution, while their differential values provide temporal information and cancel out noise. Based on this, we build a Noise-Robust Network with Spatial and Temporal Information Enhancement (NRST) as the reconstruction algorithm, which increases accuracy and robustness against noise. Both experimental and simulation results verify the proposed DoP-CACTI system's significant noise robustness and spatiotemporal enhancement properties.
