Hybrid Spectral Domain Optical Coherence Tomography Line Scanning Laser Ophthalmoscope

A method of imaging a retina of an eye, comprising:

• acquiring an OCT image of the eye by receiving, on a one-dimensional detector, a first light returning from the eye and providing a first electrical signal responsive to the first light at each of a plurality of locations along the one-dimensional detector, the first electrical signal combined with a reference signal from a reference arm, the first electrical signal and the reference signal associated with the OCT image of the eye;
• acquiring a LSLO image of the eye by receiving, on the one-dimensional detector, a second light returning from the eye and providing a second electrical signal responsive to the second light at each of a plurality of locations along the one-dimensional detector, the second electrical signal indicative of the LSLO image of the eye;
• and
• interleaving acquisition of the OCT image of the eye and the LSLO image of the eye.

An optical apparatus comprising:

• a housing;
• and
• a system of optical components disposed in the housing capable of operating in a line scanning laser ophthalmoscope (LSLO) mode and an optical coherence tomography (OCT) mode, the system of optical components including:
• a lens for converting between the LSLO mode and the OCT mode, the lens movable between a first lens position and a second lens position:
• in the first lens position, the lens receives a beam of light from a source and provides a line of light for scanning an object in the LSLO mode;
• and
• in the second lens position, the lens removed from a path of the beam of light so that the source provides the beam of light for scanning the object in the OCT mode;
• and
• a mirror for converting between the LSLO mode and the OCT mode, the mirror movable between a first mirror position and a second mirror position:
• in the first position, the mirror is removed from a path of light returning from the object;
• and
• in the second position, the mirror receives the light returning from the object.
