This research deals with developing a confocal line-scanner that combines both divided-pupil and full-pupil configurations. This combined-pupil prototype is being evaluated to determine the advantages and limitations of each configuration for imaging skin, and comparison of performance to that of a commercially available standard confocal point-scanning microscope. With the combined configuration, experimental evaluation of line spread functions (LSFs), contrast, signal-to-noise ratio and imaging performance is in progress under identical optical and skin conditions. Experimental comparisons between divided-pupil and full-pupil LSFs will be used to determine imaging performance. Both results will be compared to theoretical calculations using Fourier analysis, and to the confocal point spread function (PSF).
