Claim 15:
16. The imaging method of claim 15, wherein the delay loop comprises a path that traverses:
the first beam splitter;
a first mirror;
a second mirror;
a half-wave plate; and
a second beam splitter;
wherein the first and second mirrors are configured to direct the first percentage of the light pulse through the half-wave plate to the second beam splitter, the half-wave plate changing the polarization state of the light pulse;
wherein the second beam splitter is a polarizing beam splitter configured to receive the first percentage of the light pulse from the half-wave plate and reflect the first percentage of the light pulse having a second polarization state to the first beam splitter; and
wherein the second beam splitter is further configured to receive the light pulse from the pulse laser and transmit the light pulse having a first polarization state to the first beam splitter.
