High-speed chromatic confocal microscopy using multispectral sensors for sub-micrometer-precision microscopic surface profilometry

A full-field chromatic confocal microscopy (CCM) using a multispectral sensor was developed for quasi-one-shot microscopic 3D surface measurement. An innovative optical configuration employs a digital micromirror device (DMD) and a multispectral sensor is used to realize CCM with full-field area sca...
