Abstract

The application describes a grating storage unit (50) for light multiplexing comprising a grating imprinted or fabricated on a disc (52) or a tape and a reading head (56). The grating storage unit is characterized in that different areas of the grating have different values of the one or more of the following grating parameters: density of the grooves; groove depth, geometrical shape of the grooves, and refractive index. The grating storage unit can be optically- coupled (74) to an Attenuated Reflection (AR) probe. In embodiments of the application the AR probe is a multi-channel attenuated reflection (AR) sensor head adapted for nevi probing. The sensor head can comprise AR pin probes (82) adapted to be used as Attenuated Total Reflection (ATR) probes or Scanning Near field Optical Microscope (SNOM) pin probes. In the latter case the AR probe is used as a MIR sub cellular sensor. The grating storage unit and AR probe can be used in a system for non-mvasive assessment of the condition of a lesion.
