Abstract
A surgical imaging system is provided. The surgical imaging system includes a surgical microscope and a telecentric optical coherence tomography scanning unit configured to scan a sample through at least one optical component associated with the surgical microscope.
Claims15
A surgical imaging system comprising:
- a surgical microscope;
- and
- a telecentric optical coherence tomography (OCT) scanning unit configured to scan a sample through at least one optical component associated with the surgical microscope, the telecentric OCT scanning unit comprising an electrically tunable focusing element.
A surgical imaging system comprising:
- a surgical microscope comprising a plurality of subaperatures;
- and
- a telecentric optical coherence tomography (OCT) scanning unit configured to scan a sample through at least one optical component associated with the surgical microscope, the telecentric OCT scanning unit comprising an electrically tunable focusing element and a segmented beamsplitter configured such that each subaperture of the surgical microscope is provided with a separate beam path from the telecentric OCT scanning unit.
A surgical imaging system comprising:
- a surgical microscope;
- and
- a telecentric optical coherence tomography (OCT) scanning unit configured to scan a sample through at least one optical component associated with the surgical microscope, the telecentric OCT scanning unit comprising:
- an electrically tunable focusing element;
- a first scanning mirror having a first orientation adjustable to change a position of an OCT light beam within a scanning plane of the telecentric OCT scanning unit;
- a second scanning mirror having a second orientation adjustable to change the position of the OCT light beam within the scanning plane of the telecentric OCT scanning unit;
- and
- at least one curved mirror positioned between the first scanning mirror and the second scanning mirror on an optical path of the telecentric OCT scanning unit.
