Digital interferometric demodulation of Placido mires applied to corneal topography
Digital interferometric demodulation Placido mires corneal topography Optics
2012/4/20
This paper presents a novel digital interferometric method to demodulate Placido fringe patterns. This is a synchronous method which uses a computer-stored conic-wavefront as demodulating reference. H...
Synchronous phase-demodulation of concentric-rings Placido mires in corneal topography and wavefront aberrometry (theoretical considerations)
Synchronous phase-demodulation concentric-rings Placido mires corneal topography wavefront aberrometry Optics
2012/4/20
This paper presents a digital interferometric method to demodulate Placido fringe patterns. This method uses a computer-stored conic-wavefront as reference carrier. Even though, Placido mires are wide...
