    摘要: An image enhancement technique for use, for example in infrared or photoemission microscopy, comprises obtaining an in-focus image of the sample and an out of focus image achieved by relative movement of the sample and the microscope, and subtracting the out of focus image from the in-focus image. As a result the low frequency components are subtracted out, together with the lens and focal plane array aberrations, providing an enhanced resultant image. Because of the high levels of magnification, only small movement is required to obtain the out of focus image, allowing an enhanced image to be obtained in real time.
