問１

1. A reference voltage generating circuit comprising:a first resistance (10) having one end supplied with afirst electric potential, and another end connected to an output
terminal of a reference voltage;a second resistance (11) having one end supplied with asecond electric potential, and another end connected to theoutput terminal;
a first bipolar transistor (15) of a first polarity having
a collector supplied with the first electric potential, and anemitter connected to the output terminal;
a second bipolar transistor (16) of a second polarity
having a collector supplied with the second electric potential,
and an emitter connected to the output terminal, the second
polarity being different from the first polarity;
a first bias generating circuit (17,18) configured togenerate a first DC bias voltage and to supply the first DC bias
voltage to a base of the first bipolar transistor; anda second bias generating circuit (19,20) configured togenerate a second DC bias voltage and to supply the second DC
bias voltage to a base of the second bipolar transistor.
2. The reference voltage generating circuit according to claim
1, wherein
the first DC bias voltage has a value less than thereference voltage and not less than a voltage obtained bysubtracting a base-emitter forward voltage of the first bipolartransistor from the reference voltage, andthe second DC bias voltage has a value more than thereference voltage and lower than a voltage obtained by adding
a base-emitter forward voltage of the second bipolar transistor
to the reference voltage.

OCT (Optical Coherence Tomography), which uses thephenomenon of interference of light beams such as laser beams
to form a cross-sectional image of an object to be measured,
is now attracting attention. Applications of OCT are expected
to be developed in the medical field or in the biochemistry field,
because it is non-invasive to the human body. For example, inthe field of ophthalmology, devices for forming cross-sectional
images of the fundus, cornea, and the like have already been
put into practical use.
Patent Literature 1 discloses a device that employs OCT.
In this device, a measuring arm scans an object using a rotary
scanning mirror (galvanometer mirror). A reference arm isequipped with a reference mirror. Provided at an outlet of thedevice is an interference meter that analyzes the intensity ofinterference light of the light beams from the measuring arm
and the reference arm by using a spectrometer. Furthermore,
the reference arm is configured to change the phase of thereference light to discrete values in a step-like manner.
The device disclosed in Patent Literature 1 utilizes a"Fourier Domain OCT" method. The device irradiates the objectto be measured with a low-coherence light beam, generates
interference light by overlapping the reflected light and thereference light, obtains a spectral intensity distribution ofthis interference light and subjects it to a Fourier transform,
thereby the form in the depth direction (Z direction) of theobject to be measured being transformed into an image.

問３A

remote communication device is connected to amonitoring unit using any suitable network, such as a cellular
network and the Internet. It is needless to say that the network
includes, as other alternatives, public switched telephone
networks, radio links,services, and so forth.

himself or herself and then gives him or her instructions tocarry out a particular monitoring or measurement procedure.
The subject is told how to perform the measurement and how toconvey the result to the monitoring device.
A typical example of the monitoring unit is a remotemonitoring unit, and it may be disposed at the hospital sideof the network connection. However, this is simply by way of
example and the processing task carried out by the monitoring
unit may be carried out at any convenient point between a patientand a medical professional.
Typically, when the patientconnects using a digital device, various processing tasks may
be carried out at the user, between the user and a remote unit.
In other embodiments, the user connects manually over atelephone, in which case processing is typically carried out
at a site remote from the patient.
