Recent advancements in lidar technologies have led to significant improvements in Teledyne Optech’s airborne lidar systems. This paper will present the performance enhancements that have led to the creation of the Galaxy, a compact scanning lidar system. Unlike the previous generation of conventional airborne lidar, the Galaxy offers fundamentally improved specifications for long-range airborne lidar systems. The Galaxy system is capable of acquiring high-density, multiple-return data with unique pulse separation characteristics and exceptional precision. Utilizing discrete time-of-flight measurement electronics, this new system is capable of seamlessly operating at very high laser repetition rates through blind zones and with multiple pulses in the air. By utilizing even higher scan products , the system outperforms previous generations of systems and optimizes point density during collection.
The rapid 2-axis scanning lidar prototype was developed to demonstrate high-precision single-pixel linear-mode lidar
performance. The lidar system is a combined integration of components from various commercial products allowing for
future customization and performance enhancements. The intent of the prototype scanner is to demonstrate current stateof-
the-art high-speed linear scanning technologies.
The system consists of two pieces: the sensor head and control unit. The senor head can be installed up to 4 m from the
control box and houses the lidar scanning components and a small RGB camera. The control unit houses the power
supplies and ranging electronics necessary for operating the electronics housed inside the sensor head.
This paper will discuss the benefits of a 2-axis scanning linear-mode lidar system, such as range performance and a userselectable
FOV. Other features include real-time processing of 3D image frames consisting of up to 200,000 points per
