抄録

A differential absorption lidar (light detection and ranging) system is developed as methane leakage detector using 1.67 μm absorption band. A detection range of various 100 m and 1000 ppm·m is estimated by numerical calculation, and 30 m resolution of detection is demonstrated experimentally. Since amplifier noise and telescope misalignment spoil the sensitivity and the range of the system, solutions are also proposed. Development of a compact optical parametric oscillator for a transmitter injection-seeded by a laser diode is also reported.
