Abstract
A surgical loupe system includes one or more polarization filters for producing and/or blocking polarized light. A light source is directed through a polarization filter to a patient's tissues, producing returned light. The returned light may be magnified.
Claims25
A cross polarized inspection system, comprising:
- a source of electromagnetic radiation for irradiating an object;
- a first polarization filter between the object and the source;
- a second polarization filter arranged to receive returned electromagnetic radiation from the object;
- and
- the first polarization filter and the second polarization filter being out of phase with each other.
