Abstract (en)
[origin: WO2004065984A1] 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.
