Quantitative and qualitative measurements of odor are indispensable for the development of odor display systems that can reproduce odor at any place in any time. This chapter covers odor evaluation techniques based on human senses, instrumental analyses, odor sensors, and data analysis methods dedicated to odor measuring techniques. The chapter consists of the four following sections: sensory evaluation, gas analysis instruments, odor sensing system, and pattern analysis for odor sensing system. The first section describes odor evaluation methods with human senses. The second section gives an overview of instrumental laboratory techniques for olfaction research. The third section surveys sensor devices for odor detection. Finally, the last section gives the basic statistical methods and advanced pattern analysis for odor sensing systems.
