Abstract:
1. A scanning confocal microscope which comprises optics, including a fast scan oscillating mirror and a slow scan oscillating mirror, for directing an illuminating beam via a beamsplitter along a path to one of the fast scan oscillating minor and the slow scan oscillating mirror and then to the other of said fast and slow minors to provide a scanning beam in which said fast scan mirror oscillates to create a line scan of said beam, an objective lens having an entrance aperture via which said scanning beam is focused upon a specimen to an area thereof to be imaged and is returned to said mirrors for descanning, to provide return illumination from which a video signal is provided, said fast minor being part of a resonant scanner, and being a resonant scanning mirror having an operating resonant frequency, and said slow mirror being part of a galvanometer scanner, a frequency and phase control system responsive to the angular velocity of the fast scan mirror for providing drive pulses at a rate which drives said resonant scanner continuously at said operating resonant frequency notwithstanding changes in the actual mechanical resonant frequency of said scanner.
