Feasibility of cell-phone camera Raman spectrometer for geological samples identification in field or mobile situations

Dinesh Dhankhar and Matthew Wehner

Abstract. This note demonstrates the feasibility of integrating a Raman spectrometer in a cellphone (mobile phone) using its camera for identifying common minerals in different geologic materials. The cell phone modification is low cost (∼ $50 USD) and can be constructed by individuals, thus opening up the possibilities for "democratizing" Raman spectrometry in the geosciences and make it possible for it to be used in a wide range of field conditions (i.e., core logging, field mapping, marketplace) and combined with other data types like GPS and optical photography for added value. The combination of Raman spectra with other data and the possibility to link it through Wi-Fi or cell data to a database opens new possibilities in terms of applications. It is imagined that with suitable apps or software, it could be used by anyone since the technology and spectral hardware exist to support such devices.

Short summary
This research note demonstrates that a Raman spectrometer using the camera present in modern day cellphone can record in-situ Raman spectra of various minerals of geological importance. This allows almost anyone to be able to record Raman spectra at a very low cost.
