摘要： An OCT probe has a sheath to be inserted into a subject; and an optical system within the sheath, for changing the direction of light which propagates from a light source through an optical fiber to irradiate the light onto the subject through a transparent portion of the sheath, and for reflecting the light beam, which is reflected by the subject, to guide the light into the optical fiber. A light output surface, for causing the light to be output from the reflecting surface in a direction obliquely inclined with respect to the inner surface of the sheath, and a reflected light sheath entrance preventing portion, for preventing light reflected by the inner surface of the sheath from entering the optical fiber, are provided in the optical system. The reflected light sheath entrance preventing portion may be formed by providing a cut planar surface portion on the lens.

摘要： In an image exposing apparatus and an image exposing method, a deterioration of an image quality caused by stray light is suppressed, while both a sensitive level and a non-sensitive level are properly set in accordance with a type of photosensitive material. In the image exposing apparatus, a recording level setting unit calculates a recording level corresponding to a light amount level stored in a recording level light amount memory and sets the calculated recording level. A non-recording level setting unit calculates a non-recording level from an extinction ratio, which corresponds to a type of photosensitive material stored in a photosensitive material information memory, and the recording level. An output voltage setting unit sets an output voltage such that a detected voltage becomes equal to one of the recording level and the non-recording level.

摘要： A linearly polarized light is projected upon a recording medium of a photomagnetic type; the reflected light is rotated by an appropriate angle through a halfwave plate and split into a reflected light and a transmitted light through a beam splitter having reflection factors of 0 or 100% for p- or s-polarized light in such a way that the beam splitter functions as an analyzer for one of the reflected and transmitted lights. The other of the reflected and transmitted lights is passed through an analyzer. The two lights passed through the beam splitter and the analyzer are detected by two photodetectors separately and applied to a differential amplifier to generate a reproduction signal of high S/N ratio without the use of a half mirror R.sub.p =R.sub.s =50% which is very difficult to manufacture.

摘要： An input signal containing a base line which fluctuates to a great extent is detected or restored by comparing the input signal with reference levels which are shifted in accordance with the fluctuation of base line. The input signal is sampled at a variable sampling rate and an average of sampled values for a predetermined period is derived to produce a profile signal which resembles accurately the fluctuation of the base line. The profile signal thus obtained is added to upper and lower threshold voltages to produce the reference levels which have been corrected in accordance with the fluctuation of the base line of input signal.

摘要： In order to read out information recorded on a disc rotating at a constant angular velocity by means of a pick-up head movably arranged in a disc radius direction, a head position on the disc is detected to obtain a position signal representing a distance from a disc center to the pick-up head, and then a pulse signal having a frequency corresponding to the position signal thus obtained is generated. A detection signal supplied from the pick-up head and the pulse signal are supplied to an AND gate and pulses of the gated out pulse signal are counted by a counter. The number of the counted pulses represents correctly a length of the information recorded on the disc irrespective of position of the information on the disc.
