1. 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, said detecting light being utilized to detect an optically disturbing component; an image forming means for forming on an image receiving surface of at least one camera means 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 for generating output signals representative of said respective measured and detected images; means for deriving an interference equation descriptive of an interference given by the optically disturbing component, on the basis of the measured and detected images from the image forming means which automatically and dynamically provides a regression line as a function of each set of measured and detected images; a processor means for eliminating the optically disturbing component from the measured image on the basis of the interference equation; and a display means for providing a visual representation of an image output from the processor means.
