  • Nonlinear optical microscope
    Patent number: 5005927
    Abstract: A microscope that preferentially displays either moving or stationary objects. This all-optical device operates in real-time using the coupling of optical beams in suitable nonlinear medium such as a photorefractive crystal of barium titanate. A holographic image is continuously written and compared with the real image. For the transient detection microscope any discrepancy between the two images is immediately visible. In the stationary object enhancing microscope stationary objects are enhanced and preferentially displayed.
