Abstract
Pushbroom and flash lidar operations outside the visible spectrum, most preferably in near-IR but also in IR and UV, are enabled by inserting—ahead of a generally conventional lidar receiver front end—a device that receives light scattered from objects and in response forms corresponding light of a different wavelength from the scattered light. Detailed implementations using arrays of discrete COTS components—most preferably PIN diodes and VCSELs, with intervening semicustom amplifiers—are discussed, as is use of a known monolithic converter. Differential and ratioing multispectral measurements, particularly including UV data, are enabled through either spatial-sharing (e. g. plural-slit) or time-sharing.
