Experimental Time Resolved Methods

  • Gary R. Holtom


Recent experiments involving light scattering and diffusion in tissues show a substantial signal emerging from large tissue masses on the order of 2–10 nanoseconds (ns) following light entry. A quantitative method for resolving the scattered light should have these attributes:
  1. a)

    High sensitivity. This implies a quantum limited detector such as a photomultiplier tube (PMT).

  2. b)

    Good dynamic range, ideally five decades if needed.

  3. c)

    Stable, linear, and adjustable time sweep for convenient comparison of data to theoretical models.
