About

R. Sudharsanan is a leading researcher in optoelectronics and photonic systems, with a primary focus on developing compact, high-performance sensing technologies for autonomous systems and defense applications. His work centers on two key areas: MEMS-based scanning LADAR (Laser Detection and Ranging) systems and low-noise avalanche photodiodes (APDs) for short-wavelength infrared (SWIR) detection. His most impactful contribution is the development of a low-cost, compact MEMS scanning LADAR system for robotic applications, published in 2012 and cited 62 times. This work, conducted at the U.S. Army Research Laboratory in collaboration with Boeing Spectrolab, demonstrated a practical, eye-safe solution for autonomous navigation in future robots and vehicles—addressing a critical need for affordable, miniaturized sensing. Additionally, his research on SWIR APDs, with 10 citations, has advanced the sensitivity of detectors used in eye-safe laser ranging and robotic vision by tackling the challenge of excess noise in InGaAs APDs. Sudharsanan’s contributions bridge the gap between laboratory innovation and real-world deployment, making him a notable figure in the fields of autonomous systems and photodetector technology. His work continues to influence the development of next-generation sensing platforms for robotics and defense.
