A single wavelength, dual temporal offset module for AOSLO systems

We designed a generalizable module enabling dual temporal and spatial offset imaging. Two optical channels are generated from a single input. At a single focus these can be used for blood flow calculations and template free imaging. The system is supported by custom APDs detector systems. Each of the optical channels is imaged onto five detectors through a 1-to-5 fiber bundle to acquire images from one confocal and four offsets apertures. The module can be added to existing AOSLO systems at pupil conjugate planes. Examples of customizing the module for the Indiana AOSLO and APAEROS systems are presented.
