Abstract Mental stress will not only reduce the work performance, but also lead to cardiovascular diseases and psychological disorders. The article first addressed four types of psychological stress assessment methods: stress appraisal measurement, affective responses measurement, stress hormones measurement and cardiovascular response measurement, as well as their advantages and disadvantages. Then a facial Transdermal Optical Imaging technique was introduced to monitor people’s real-time dynamic changes in mental stress level remotely. The novel technique uses a conventional digital camera to video record the people’s faces from a distance, analyzing the hemoglobin concentration changes underneath the facial skin to obtain the physiological indices of mental stress, such as heart rate variability (HRV) etc. Therefore, it can be widely used in scientific research and practical applications, such as medical monitoring, psychological research, marketing etc.
