Spectroscopic measurements are described based on light-molecule interaction in response to a resonant rate optical pulse train so that a Raman spectrum is reflected containing at least two types of vibrational mode information (e.g., vibrational frequency, and vibrational phase relaxation) on the molecules comprising the object. A pump optical pulse train generation means is configured for generating an optical pulse train having an arbitrary repetition rate which is directed through irradiation means to the sample object. Light from the sample object is collected and vibrational coherence is detected for the sample object. The sample is tested across a plurality of different repetition frequencies. The detected information can be compared with data from other known samples from within a database when analyzing the information collected. |
