Optical microscopy presents an extension of standard methods for pore space description. In this paper two examples of application in materials and mechanical engineering are introduced. The porosity and pore size distribution of two types of AAC are measured. In the second example the thermally induced cracks of cement fiber composite are visually detected and mathematically described. The technology of sample preparation, measurement technique and digital image processing is described, while advantages and disadvantages are discussed.
