摘要： Low coherence light having a central wavelength λc of 1.1 μm and a full width at half maximum spectrum Δλ of 90 nm is emitted. The low coherence light has wavelength properties suited for the light absorbing properties, the diffusion properties, and the dispersion properties of living tissue. A light dividing means divides the low coherence light into a measuring light beam, which is irradiated onto a measurement target via an optical probe, and a reference light beam that propagates toward an optical path length adjusting means. A multiplexing means multiplexes a reflected light beam, which is the measuring light beam reflected at a predetermined depth of the measurement target, and the reference light beam, to form coherent light. A coherent light detecting means detects the optical intensity of the multiplexed coherent light. An image obtaining means performs image processes, and displays an optical tomographic image on a display apparatus.

摘要： A fluorescent-light image obtaining apparatus for obtaining an autofluorescent-light image emitted from a target tissue irradiated by an excitation light, wherein the safety of the patient is ensured against injury from exposure to excessive excitation light when the distance between the output end of the excitation light projector and the target tissue is short. A contact detector detects that the end of the excitation light projector of the endoscope is in contact with the target tissue. Then, an excitation light output controller receives a signal indicating that the end of the excitation light projector is in contact with the target tissue. In response to this signal, the excitation light output controller stops the emission of the excitation light, or reduces the intensity of the emitted excitation light to a safe intensity for the patient even while the end of the excitation light projector and the target tissue are in contact.

摘要： An optical tomographic image obtaining apparatus, capable of obtaining optical tomographic images at high resolution, is miniaturized. During obtainment of an optical tomographic image, a mirror rotating section rotates a mirror, to rotate the irradiation direction of a measuring light beam. Operations of an optical path length changing section are controlled such that a measurement point along the optical path direction is moved for every rotation of the irradiation direction. A sheath rotating section rotates a sheath to move the position of a lens fixed within a lens holder by a threaded mechanism, to move the focusing position of the measuring light beam in the optical path direction, to match the position of the measurement point. Therefore, the movement speed of the focusing position can be reduced compared to conventional apparatuses. Accordingly, the necessity of a large focusing position moving means, which is capable of high speed movement, is obviated.
