Abstract
A method of detection of the time-varying intensity distribution with CCD image sensors is proposed. It is confirmed that the time-varying intensity can be reconstructed from the temporal output of a photodetector element which is produced by integrating the time-varying intensity over the period of charge storage. This detection method is applied to measurement of the optical surface profile using sinusoidal phase-modulated laser light.Keywords
