Abstract

A triple view imaging apparatus is provided for measuring quantitative distribution of material or property in a sample. In the triple view imaging apparatus, an optical system receives an original optical image of the sample, separates the original optical image into at least two secondary optical images having different optical properties from one another, and projects the at least two secondary optical images into a single view angle. A single video camera simultaneously picks up the thus projected plurality of secondary optical images as a single composite image and produces image signals representing the light intensities of the plurality of secondary optical images. An image processor receives the image signals and processes the image signals to obtain final image signals representing a relationship between the image signals for respective ones of the plurality of secondary optical images. An image display receives the calculated final image signals and displays a tertiary optical image based on the calculated final image signals which defines quantitative distribution of material or property in the sample.
