<p>In an optical diagnosis and treatment apparatus including a pulsed light source (10), an illumination optical system (15) for illuminating a region (11) of a living body through a guide tube (12), a light condensing means (16), an optical scan means (17), a light detection means (24) for detecting the pulsed light (14) reflected from the region (11), an operation means (29) for reconstructing, based on an output from the light detection means (24), a tomographic image of the region (11), an image display means (30) for displaying the image based on an output from the operation means (29) and a light intensity switching means (25, 51) for switching the intensity of the pulsed light (14) at least between a level at which vaporization of living body tissue due to multi-photon absorption occurs at a convergence position of the light (14) and a level at which vaporization does not occur.</p> |
