Photoacoustic microscopy of coal macerals. Annual report Jan-Dec 82

Technical Report ·
OSTI ID:5814899
The overall objective of the project is to develop photoacoustic microscopy as a new technique for delineating the thermal-elastic and chemical properties of coal macerals. This petrographic information is expected to play a role in the characterization of coal for any process where the properties of the coal determine the behavior of the process. To characterize coal properly, both its chemical composition and its rank must be known. Photoacoustic microscopy offers a potentially useful technique for probing the chemical properties of coal macerals. The major result achieved has been the development of a photoacoustic/reflectance microscope capable of obtaining thermal and optical data from the same coal macerals.
