1. An optical probe comprising:
an optical housing extending from a proximate end to an opposing distal end;
a transmitting lens disposed at the distal end and configured to output a first transmitted signal beam having a first transmission axis and a second transmitted signal beam having a second transmission axis, the first transmission axis and the second transmission axis being different; and
a receiving lens disposed at the distal end and configured to receive a first reflected signal beam and a second reflected signal beam corresponding respectively to the first transmitted signal beam and the second transmitted signal beam,
wherein the optical housing has formed therein a transmitting optical channel configured to communicate an input optical signal from the proximate end to the transmitting lens, and a receiving optical channel separated from the transmitting optical channel to communicate the first reflected signal beam and the second reflected signal beam to the proximate end.
