title = "DMD as a Pseudo-Pixel Array for Long-Range High-Speed LIDAR",
abstract = "Long-range, high-speed, free-space LIDAR systems face challenges from ambient background noise. Maximizing the signal-to-noise ratio (SNR) is vital for extending the range and increasing the scanning speed. One effective strategy in steered LIDAR systems is using field-of-view (FOV) filtering to retain signals and suppress noise. Pixel-based approaches with sensitive detector arrays are costly, especially at near-infrared wavelengths. This work employs a digital micromirror device (DMD) as a pseudo-pixel array. It redirects signal light to a single-pixel detector while routing noise light to a beam dump. This work explores a simple experimental setup to explore the DMD{\textquoteright}s range improvement potential. Ambient noise rejections ratios greater than 20 were exhibited using a 6×6 pseudo-pixel array on the DMD, resulting in a 1.97 fold range improvement in a theoretical LIDAR system. This approach thus offers a means of enhancing long-range, high-speed, free-space LIDAR systems.",
