  • Publication number: 20140046409
    Abstract: Disclosed herein is a light source apparatus for photo-diagnosis and phototherapy. The light source apparatus includes a first light source, a second light source, a light-guide, an interference filter, and a compensation filter. The first light source is non-coherent, and the second light source is coherent. The light-guide delivers light emitted from the first light source and the second light source. The interference filter is disposed on an optical path of the first light source. The compensation filter is disposed between the first light source and the light-guide, and compensates for an output spectrum of the first light source and converts the output spectrum of the first light source into a predetermined reference output spectrum. Here, the light emitted from the second light source is reflected by the interference filter to be incident to the light-guide and the light from the first light source passes through the interference filter at the same time.

  • Publication number: 20100241025
    Abstract: The present invention provides a cold reflex tester, in which an electrical device capable of controlling the temperature and maintaining a fixed temperature at a low level based on an electrical signal from a controller is used in a cold stimulator that is brought into contact with a subject's body as a means for applying a cold stimulus to the subject's body. Thus, it is possible to apply a more constant stimulus to a subject's body during measurement and thus improve the reliability of the measurement.

  • Publication number: 20090093868
    Abstract: The present invention provides a laser apparatus for medical treatment using pulse trains, in which the skin is cooled to a given temperature and then one or more laser pulses are applied to a to-be-treated region at specific intervals, thereby alleviating a pain associated with a skin disease and activating a dermis layer. According to the present invention, a pain caused during the treatment process is alleviated by using laser pulse trains and a cooling unit, and heat energy is transferred to only a dermis layer of a to-be-treated region without eliminating an epidermis layer of the to-be-treated region, thereby remarkably improving the treatment recovery period and the frequency of treatments as compared to the conventional treatment method.
