A possibility of the amplification of image brightness by the active medium of the photodissociative iodine laser have been demonstrated. The brightness of the test-object image with spatial frequency of 10 mm-1 was amplified 1600 times for Q-switch lasing action and 250 times for free- running one. The contrast of amplified image was equaled 0.8 in both occasions. The smallest input signal achieved the level of 10-13 J per pixel.
