Paper Abstract

Gabor domain optical coherence microscopy (GD-OCM) is an emerging tomographic imaging technique that overcome the depth of focus (DOF) limit of high numerical objective lens by acquiring multiple cross-section images corresponded with different focal planes of the objective along an axial direction and combining them to form an invariant high resolution cross-section image. We previously reported an alternative processing method of GD-OCM called spectral fusing GD-OCM (SF-GD-OCM). SF-GD-OCM extracts in-focus information directly from acquired spectral interference signals. The advantage of SF-GD-OCM over the original GD-OCM is that the Gabor filtering and fusing can be implemented in an acquisition hardware instead of a host computer. Here, we have investigated the implementation of SF-GD-OCM by using FPGA frame grabber. The experimental setup of the acquisition system as well as the implementation of the spectral Gabor fusion in FPGA device have been developed and verified. Results show that the data processing of SF-GD-OCM in FPGA enabled acquisition device is possible and could lead to improvement in overall imaging speed of GD-OCM.
