Abstract
An image analyzing apparatus comprising a source of light for radiating a target object of interest, a measuring light of a first predetermined wavelength and at least one detecting light of a second predetermined wavelength different from the first predetermined wavelength, which detecting light is utilized to detect an optically disturbing component, a camera unit for forming a measured image of the target object radiated by the measuring light and a detected image of the target object radiated by the detecting light, and capable of generating output signals representative of the respective measured and detected images, a processor for deriving an interference equation descriptive of an interference given by the optically disturbing component, on the basis of the measured and detected images outputed from the camera unit, a computer for eliminating the optically disturbing component from the measured image on the basis of the interference equation, and a display device for providing a visual representation of an image output from the computer.
