Abstract A prototype lidar for measuring the spatial distribution of suspended particulate matter(aerosol) in indoor factory workplaces was built and evaluated in a laboratory. The lidar is a Mie scattering lidar using a third harmonic laser-diode pumped Nd:YAG laser(355 nm). The transmitter and receiver were composed on an optical breadboard and manually scanned on a tripod. The lidar data were recorded together with the angular data from a gyro sensor, and the aerosol distribution was displayed in nearly real-time. The sensitivity was evaluated by measuring the distribution of smoke from incense sticks placed in the laboratory. Based on the results, the possibility of downsizing the lidar system was discussed. Also, a method was studied to display the aerosol distribution in a 3D space in combination with a small hard-target LiDAR commercially available. |
