摘要： An imaging apparatus includes a light source; a first beam splitter for reflecting a projection beam emitted by the light source; an objective lens unit including a reflection reference surface for reproducing the projection beam into a measurement beam projected onto an object to generate a first reflection beam and a reference beam projected onto the reflection reference surface to generate a second reflection beam mixing with the first reflection beam and passing through the first splitter and forming an operating beam; a second beam splitter for modulating the operating beam into first and second sub-beams; a monochrome image detection device for passage of the first sub-beam to obtain an interferometric image with monochrome from a first interference region; and an image detection device for permitting passage of the second sub-beam in order to obtain a non-interferometric image from a second interference region.
