Teledyne Optech has added a high-performance scanner update to its line of airborne laser terrain mappers, the Optech Galaxy ALTM. The Galaxy’s scan efficiency has been engineered to deliver an additional 30 percent boost to its area coverage rates. When coupled with its SwathTRAK and PulseTRAK technologies, collection efficiencies exceeding 70% percent are possible, relative to the traditional fixed-FOV dual-beam sensors currently on the market.

“Operational cost reduction is a key driver for our clients. This new enhancement releases underlying performance in an already robust scanner design to enable significant increases in scan velocity and scan product. This translates to improved XY point distribution at higher laser PRF sample rates, faster aircraft speeds and wider scan FOVs, as well as dramatic increases in point density at lesser FOVs,” says Michael Sitar, Teledyne Optech’s airborne business manager.”

SwathTRAK leverages a programmable galvanometric scanner by dynamically adjusting the scan FOV during flight and data acquisition, enabling fixed-width data swaths even in variable terrain. The advantage is fewer flight lines and more consistent point distribution, whether on hill peaks or valley bottoms.

PulseTRAK enables a continuous operating envelope, thereby solving the multipulse challenge of data coverage gaps and density variation in the multipulse transition/blind zones. This gives surveyors the ability to use very high laser pulse rates and generate high point density in variable terrain without the need for complex flight planning.
