ABSTRACT:
A light microscope comprises a light source and a first acousto-optic tunable filter responsive to the light source for producing two light streams of different polarization. A control circuit is provided for tuning the first filter to a plurality of frequencies. A mechanism, such as steering optics, is provided for combining the two light streams into a combined light stream. Input optics focus the combined light stream. A condenser, such as a darkfield condenser, receives the focused, combined, light stream and projects it onto a sample. A second acousto-optic tunable filter is responsive to light from the sample. A second control circuit is provided for tuning the second acousto-optic filter to a plurality of frequencies. The light from the second acousto-optic tunable filter may be captured and stored for future processing.
