Abstract :
A compact novel form of confocal scanning microscope using a semiconductor laser is described. Confocal operation is ensured by the use of a single mode optical fibre for both launching the light into the microscope and collecting the signal from the object. The collected light is allowed to reenter the laser and the image is detected as a modulation on the signal from the laser power monitor diode.
