A Laser Induced Fluorescence Spectrum (LIFS) is useful for object identification, and LIDAR is powerful in the remote distribution monitoring of objects. We developed a LIFS-LIDAR system whose characteristics allow it to be a potential apparatus for environmental observations. Our system consists of a UV (355 nm) pulse laser, a 25-cm diameter telescope on an altazimuth mount, and a multi-channel spectrometer equipped with a gated image-intensified CCD. To observe low LIFS signal objects even during the daytime, the CCD’s gate-open time width was set to 10 ns to reduce the background light noise. The gating was delayed to coincide with the fluorescence arrival time to the CCD, which provided information on the object distribution. System performances were checked by the monitoring fluorescence spectra of a living plant and a wooden board inside a room under a natural light condition. The plant had fluorescence peaks at around 420, 680, and 740 nm; however, the wooden board only had a peak at around 420 nm, showing that LIFS is a good indicator for object identification. Our system’s volume, 1280 × 830 × 990 mm, was so compact that it was easily carried by a compact vehicle; we also prepared a small dynamo. Our mobile LIFS LIDAR will allow observations more freely any time.
