    摘要: The invention provides for phase measurement in transmission and reflection scanning optical microscopes. In these microscopes a parallel beam of laser (1) light is focused onto a small portion of an object (4). Light from this small portion is imaged via a pinhole (8) onto a single detector (10). The image is built up by scanning the object and recording the output from the detector for each object position. In this invention the phase image is recovered by subsequent processing of two or more amplitude images. One image is measured in the usual way; the other or others are recorded with suitable filters (2, 7) placed in the Fourier or output planes of both the illumination (3) and imaging (6) lenses. The two optical filters (2, 7) have amplitude weighting functions g(x, y) which preferably equal c. exp(ax + by), where a, b and c ar real constants.

    摘要: The invention improves the resolution in a scanning confocal microscope by performing optical signal processing prior to detection. Such processing is achieved by an element (7, 39, 42) having either or both phase and amplitude weighting. The microscope may be a transmission, reflection, or fluorescent microscope. In a transmission microscope a laser (1) illuminates a small area of a sample (3). Light from this small area is focussed onto an optical processing element (7). Output from the element (7) is detected by a detector (11) via a pin hole (9) in a stop plate (10). Phase weighting of the element (7) may be formed by a rectangular grating (15), and amplitude weighting formed by a sinusoidal variation in absorption. One optical weighting function m(x, y) is cos (2 pi Nx/ lambda ).cos(2 pi Ny/ lambda ), where N is the numerical aperture of lenses (2, 6) and lambda is wavelength. An alternative optical weighting function m(x, y) is sign (cos(2 pi Nx/ lambda )).sign (cos(2 pi Ny/ lambda )).
