Title: Mark D Entwistle: Innovator in LiDAR Technology

Introduction

Mark D Entwistle is a notable inventor based in Feasterville-Trevose, PA (US). He has made significant contributions to the field of LiDAR technology, holding a total of 4 patents. His innovative work focuses on enhancing the capabilities of LiDAR systems, which are crucial for various applications, including mapping and object detection.

Latest Patents

Among his latest patents is a LiDAR system comprising a single-photon detector. This invention discloses a method for developing a map of objects in a region surrounding a location. The method involves interrogating the region along a detection axis with a series of optical pulses and detecting reflections from objects located along that axis. A multi-dimensional map is created by scanning the detection axis in at least one dimension. The reflections are detected using a single-photon detector that employs a sub-gating scheme, allowing it to selectively detect photons from reflections originating within defined zones of the detection field. The optical pulses used have a wavelength range of 1350 nm to 1390 nm, which is known for its high eye-safety threshold and low solar background.

Another significant patent by Entwistle involves a Geiger-mode avalanche photodiode-based receiver with multiple-return capability. This invention describes LiDAR systems that interrogate a detection region with a periodic series of optical pulses. The receiver consists of multiple Geiger-mode avalanche photodiode-based pixels that can asynchronously disarm and rearm after detecting a reflection. This capability allows each pixel to detect multiple reflections of the same optical pulse during a single detection frame, thus enhancing the system's efficiency and accuracy.
