Abstract:
Devices, systems and methods for use in confocal imaging systems are described that enable lateral and axial scans at high speeds and without a moving scanner while producing high quality images. One chromatic confocal optical head includes an illumination source, such as an addressable point source array, to provide a wide spectrum illumination including multiple wavelengths. The optical head also includes a beamsplitter to allow the light to be directed toward an object, to receive the reflected light from the object and to direct the reflected light toward a detector. The optical head further includes a pinhole mask that is positioned to receive the light that is reflected from the object after passing through the beamsplitter, and a dispersion element that is positioned to receive the light after passing through the pinhole mask, and to separate the light into multiple spectral components for reception by the detector.
