WebThe light section is a technology for optical 3-D measurement, which makes the measurement of a height profile along a projected line of light. It is based on the principle … Webtechniques, e.g. [4]. With such methods the wide-field illumination means that fluorescence images can be rapidly acquired using low excitation intensities, however, the unwanted out-of-focus light is still detected by the CCD camera and this degrades the signal to noise ratio in the final image compared to ‘true’ optical sectioning techniques.
