ABSTRACT:
A scanning laser microscope capable of detecting a fine structure producing low contrast and easily measuring the length, the volume, and so forth of an object. A laser beam is focused onto the object. The beam is scanned at regular intervals, or in a digital fashion, in two dimensions. Light scattered from the object is detected by a detector to observe an image of the object. The output signal from the detector is digitized into a given number of gray levels in synchronism with the digital scans. The object image can be stored in a memory and processed while correlating the scanned position with the intensity of the scattered light at this position.
