  • Patent number: 10925534
    Abstract: The present invention relates to a skin measurement device capable of measuring information related to the skin. The skin measurement device capable of transmitting and receiving data to and from a skin treatment device, according to one embodiment of the present invention, comprises: a sensing unit formed so as to sense information related to the skin; and a control unit for controlling the sensing unit such that the sensing unit senses information related to certain skin, on the basis of contact between the skin measurement device and the certain skin, wherein the sensing unit is formed so as to emit light on the certain skin and to sense the information related to the certain skin on the basis of light reflected from the certain skin.

  • Patent number: 10835124
    Abstract: Disclosed is a polarization sensitive optical coherence tomography apparatus and control method thereof. According to the polarization sensitive optical coherence tomography apparatus and control method thereof of the present invention, the local phase delay value of each layer of a multiple of layers using Jones matrix for a birefringent material having the multiple of layers where each layers optical axis is random based on a polarized signal detected in an optical detector may be calculated. According to the present invention, a skin aging level can be accurately examined by obtaining an accurate accumulated phase delay value for a multiple of layers of birefringent material having a random optical axis.

  • Patent number: 10264973
    Abstract: According to one embodiment, an Optical Coherence Tomography (OCT) device includes: a light source; a mirror to reflect a light from the light source; a light receiver to output the light from the light source to skin and receive a light reflected from the skin; a detector to detect an interference signal between the light reflected from the mirror and the light received by the light receiver; an image sensor to convert the detected interference signal into an image signal; a processor to output a second signal by filtering a first signal based on the image signal, calculate an error by using the first signal and the second signal, and output an error-compensated image by compensating for the calculated error; and a display to display the error-compensated image. In this configuration, the OCT device may reduce noise caused by the image sensor, to display a skin image with improved quality.
