1. An apparatus comprising:

  • at least one first arrangement configured to receive at least one first electro-magnetic radiation provided from a sample which is based on at least one second electro-magnetic radiation forwarded to the sample, wherein the at least one first electro-magnetic radiation has a first frequency and the at least one second electro-magnetic radiation has a second frequency which is different from the first frequency, and wherein a difference between the first and second frequencies is based on an acoustic wave inside the sample related to at least one characteristic of the sample;

    at least one second arrangement configured to receive at least one third electro-magnetic radiation from the at least one first arrangement which is based on the at least one first electro-magnetic radiation and separate the at least one third electro-magnetic radiation into a particular finite number (N) of frequency component radiations; and

    at least one third arrangement configured to receive a particular energy of more than 1/N of energy of the at least one third electro-magnetic radiation, and generate information associated with the sample.
