Device for evolutive illumination of an object |
摘要 |
A device is provided for the prolonged illumination of an object from an initial transitory illumination. This device comprises a laser whose cavity is closed by two total reflection mirrors; in the path of the intra-cavity radiation is disposed a photoexcitable interaction medium with index variation in the volume of which the transitory signal wave coming from the object and the intra-cavity radiation interfere; this interference generates in real time an index strata grating which diffracts a complex conjugate wave of the signal wave which returns to the object.
