    Abstract A novel light detection and ranging (LiDAR) design was proposed and demonstrated using just a conventional global shutter complementary metal-oxide-semiconductor (CMOS) camera. Utilizing the jittering rising edge of the camera shutter, the distance of an object can be obtained by averaging hundreds of camera frames. The intensity (brightness) of an object in the image is linearly proportional to the distance from the camera. The achieved time precision is about one nanosecond while the range can reach beyond 50 m using a modest setup. The new design offers a simple yet powerful alternative to existing LiDAR techniques.

    We demonstrate an improved two-camera system for multi-mass and multi-hit three-dimensional (3D) momentum imaging of ions. The imaging system employs two conventional complementary metal–oxide–semiconductor cameras. We have shown previously that the system can time slice ion Newton spheres with a time resolution of 8.8 ns, limited by camera timing jitter [J. Chem. Phys., 158, 191104 (2023)]. In this work, a jitter correction method was developed to suppress the camera jitter and improve the time resolution to better than 2 ns. With this resolution, full 3D momentum distributions of ions can be obtained. We further show that this method can detect two ions with different masses when utilizing both the rising and falling edges of the cameras.
