Disease diagnosis and skin age measurement apparatus using laser irradiation device and detachable handpiece used in the same

A disease diagnosis apparatus for collecting light which is generated when light is projected onto body tissue and diagnosing a disease, the apparatus comprising:

• a first light collection unit configured to collect a part of the generated light;
• a second light collection unit configured to collect a part of the generated light;
• a spectrometer configured to analyze a spectrum of the light which is collected by the second light collection unit;
• a spectrum data comparison unit configured to compare the spectrum analyzed by the spectrometer and reference spectrum data;
• a CCD configured to convert the light collected by the first light collection unit into a digital image;
• an image data comparison unit configured to compare the digital image converted by the CCD and a reference image;
• and
• a disease diagnosis unit configured to determine whether there is a disease in the body tissue based on at least one of a comparison result of the spectrum data comparison unit and a comparison result of the image data comparison unit,
• wherein the light projected onto the body tissue is a collimated light.

• a connection part detachably connected with the laser irradiation device;
• a CCD disposed in the body part to generate a digital image;
• and
• a light collection unit configured to split the generated light entering through the generated light entering part into a spectrometer and the CCD,
• wherein the CCD is configured to generate the digital image corresponding to the light provided from the light collection unit, and
• wherein the laser projected onto the body tissue by the laser irradiation device is a collimated beam,
• wherein the light collection unit comprises:
• an optical module configured to split at least part of the generated light entering through the generated light entering part into a first direction and a second direction, and transmit the light;
• an optical module configured to provide the light transmitted in the first direction to an optical fiber connected to the spectrometer;
• and
• an optical module configured to provide the light transmitted in the second direction to the CCD.
