A vibrometer for probing an object to determine its vibratory signature and a method of probing same. The vibrometer includes a laser for generating a laser beam for probing the object; a detector for detecting reflections from the object; and a two beam input phase-conjugate mirror located so as to receive a portion of the laser beam produced by the laser and a portion of the laser beam reflected from the object, the two input beam phase-conjugate mirror reflecting received diffuse signals from the object back towards the object.

Un vibrómetro para sondar un objeto para determinar su firma vibratoria y un método de sondar iguales. El vibrómetro incluye un laser para generar un rayo laser para sondar el objeto; un detector para detectar reflexiones del objeto; y una entrada de dos vigas fase-conjuga el espejo localizado para recibir una porción del rayo laser producido por el laser y una porción del rayo laser reflejado del objeto, la viga entrada dos fase-conjugue el espejo que refleja señales difusas recibidas del objeto detrás hacia el objeto.
