Abstract: PURPOSE:To obtain a light source for a wavelength multiplex optical communication having stable frequency, narrow frequency interval and high multiplex by providing three lenses and one plane diffraction grating out of a plurality of LDs, LD optical fiber, and a plurality of reflecting mirrors, composing an optical resonator having frequency selectivity out of the LD and independently and selectively single-mode oscillating the plurality of LDs. CONSTITUTION:The output light of LD1 is fed through an optical fiber 2 to become a parallel beam by a lens 3, diffracted by a diffraction grating 4, and condensed at a position corresponding to the wavelength on a focal point surface of a condensing lens 5. When a reflecting mirror 6 is disposed at the position corresponding to the specific wavelength, an external optical resonator is formed only for the specific wavelength. The resonance frequency is varied by altering the position in (x'-y') plane of the mirror 6, and the oscillating frequency of the LD1 can be changed in a range of a gain. Accordingly, when a wavelength multiplex optical communication light source is required, the mirror 6 is arranged in two-dimensions in x'-y' plane, and the external optical resonator may be formed.

Abstract: PURPOSE:To measure the reflecting surface precision of a 2nd reflecting mirror with good precision by forming plural holes in the skin, core material, and adhesive on a back surface side at a position where the reflecting surface preci sion of the 2nd reflecting mirror is measured. CONSTITUTION:At the position where the reflecting surface precision of the 2nd reflecting mirror is measured, the holes are bored in the skin 20b, adhesive 22b, and core material 21 on the back surface side and the adhesive 22a on the opening side.

Title: Method of automatic focus depth control in medical shadowless lighting equipment
Inventor: KATO YASUHIRO
IPC: A61B19/00
Filed: 1987-11-04
Abstract: PURPOSE: To provide a method for adjusting automatically the depth of focus in a medical astral lighting system so as to perform automatic focus movement along the Z axis, including the steps of: receiving reflected light from an under-operation site which is illuminated with light emitted from a light emitting device with a photodetector for the Z axis; moving a direction of this photodetector and a direction of an illumination bulb with respect to an axis of moving focus; and moving a focus automatically along the Z axis. CONSTITUTION: When light reflected from an under-operation site M is received by an optical receiver 7 for the Z axis, signal processing is performed in the optical receiver 7. If light detected by the optical receiver for the Z axis 7 is in a positive region (+Z), a Z axis driving motor is driven via a control circuit and a direction of an illumination bulb 2 is moved until the light is imaged on a point Q of a sensor 12 of the optical receiver 7 for the Z axis. Moreover, if light detected is in a negative region (-Z), the Z axis driving motor is also driven and a direction of the illumination bulb 2 is moved until the light is imaged on the point Q of the sensor 12 of the optical receiver 7 for the Z axis similarly.  If an up button or a down button of a switch is switched on, during the switch is being operated, the Z axis driving motor is driven via an output control circuit and the focus is sent up or sent down along the axis of moving focus (b). Through these movements, the focus is moved automatically along the Z axis without fail with respect to the under-operation site.
