Abstract

Amplitude and phase measurements of small particles using a wide field, phase measuring confocal microscope are demonstrated. The wide field confocal capability of the microscope is achieved by illuminating both sample and reference arms of a Linnik interferometer with a moving speckle pattern. In addition a rigorous vector diffraction microscope model based upon Mie scattering theory has been developed. The model is particularly useful as by careful consideration of the scattered and unscattered light, quantitative transmission images can be achieved.
