Industrial fiber lidar: some applications

摘要

In recent years, INO has developed an eye-safe, transportable industrial fiber lider (IEL) for industrial applications of pollution control during handling of losse materials~(1-2). However, it can also be used for other applications like urban particulates monitoring, cloud mapping, and unattended surveillance. The IFL is a compact and direct scanning lidar. It is based on INO"s diode pumped Erbium doped fiber laser, which delivers an energy of 1.5 microJoules in 12ns pulses with a high repetition rate of 10kHz at an eye-safe wavelength of 1.5microns. INO's lidar system is composed of a lidar head containing the transmitter-receiver optics in a biaxial configuration mounted on a scanning platform. The lidar head is connected to the laser source and detector via optical fibers. A computer controls the scanning platform via an optical RS-232 communication link. This allows remote operation since sensitive equipment like the laser and the computer can be located away from the surveillance site in an environmentally controlled froom. The IFL characteristics and results obtained from monitoring in an urban area and field trials on surveillance of hard targets and trnasmission through obscurants will be detailed.
