摘要： Apparatus, method and data processing for increasing the depth range and signal to noise ratio (SNR) in Fourier domain low coherence interferometry (FD LCI) and in Fourier domain optical coherence tomography (FD OCT) using a 2 dimensional (2D) detector array is provided. The depth range and the noise of the FD LCI and FD OCT depend on the number of pixels in the detector that are used for imaging. As the depth range is proportional and the noise is inversely proportional to the number of pixels, the use of increased number of pixels of a 2D detector array increases the depth range and the signal to noise ratio (SNR) many fold.
