An infrared thermographic camera is a device that forms an image using infrared radiation, similar to a common camera that forms an image using visible light. Instead of the 400–700 nanometer range of the visible light camera, infrared cameras operate in wavelengths in the thermal infrared. The photo below shows the Parthenon's infrared photo.

Differential Optical Absorption Spectroscopy (DOAS)

  • By: apdlidar

The aim is to identify and measure concentrations of different gases using the Differential Optical Absorption Spectroscopy (DOAS), which is based on Beer-Lambert’s absorption law. It states the relationship between the quantity of light absorbed and the number of molecules in the light path where travels the optical beam.

The DustTrak™ I, II Aerosol Monitors 8520 and 8530 are desktop battery-operated, data-logging, light-scattering laser photometer that gives you real-time aerosol mass readings. It uses a sheath air system that isolates the aerosol in the optics chamber to keep the optics clean for improved reliability and low maintenance. They can measure aerosol concentrations corresponding to PM1, PM2.5, Respirable, PM10 or size fractions

GRIMM EDM 365 Transportable Outdoor Environmental Dust Monitor simultaneously measures the PM10, PM2.5, PM1 values every sixty seconds and displays them as number concentration (number of particles/m³).  The aerosol spectrometer works at a flow rate of 72 liters/minute. The constant flow rate is maintained by a large external flow controlled pump. Sheath air assures cleaning of the optic which means extended periods of remote operation are assured.

AIAS is a mobile depolarization lidar employed for detecting the polarized and cross polarized backscattered lidar signals at 532 nm, to further characterize the shape of the sampled particles. The calibration technique applied in this system is the ±45o calibration method, introduced by Freudenthaler et al. (2009).
