In the coded aperture compressive temporal imaging, multi-frame images can be reconstructed from a single-shot coded image. For increasing the reconstructed image quality, we have proposed a method for simultaneously acquiring the complementary coded images from two paths using the optical system composed of dual lens and a digital micro-mirror device. On the other hand, when we use the random coding patterns for acquiring the coded images, the amount of calculation increases, and long calculation time for the reconstruction process of compressive sensing is required. In this study, we propose a new coding pattern and a reconstruction method for increasing the calculation speed.
