Damien P. Igoe, Alfio V. Parisi and Brad Carter Evaluating UVA Aerosol Optical Depth using a Smartphone Camera Photochemistry and Photobiology 89
An enlarged image taken of the sun using the LG Optimus smartphone camera at a wavelength of 380 nm. The image was achieved using attached narrowband and neutral density filters. The grayscale response can be used to determine the solar irradiance and aerosol optical depth with a high level of accuracy when compared with the readings obtained from a Microtops II sunphotometer.
