Diagnostic method and apparatus using light
First Claim
1. A diagnosis apparatus using light, comprising:
- an input/output unit for receiving a command for measurement from a user and for providing information on the result of a measurement to the user;
a control unit for receiving the command for measurement from the input/output unit and for generating a control signal;
a light generating unit for generating at least two light beams, each light beam having an initial intensity, for measurement according to the control signal;
a light receiving unit for detecting the intensity of each of the at least two light beams after transmission through an object that is subject to measurement and for converting the received light beams into electrical signals; and
a data processing unit for processing the electrical signals received from the light receiving unit and for outputting information on the result of a predetermined measurement to the input/output unit.
