Abstract: According to an embodiment of the present disclosure, there is provided a laser spectroscopy-based independent device, including: a spectrometer configured to measure a spectrum of generated light which is generated by a laser projected onto a sample; and a disease analysis module configured to determine whether there is lesion tissue by applying a lesion tissue detection learning model to a result of non-discrete spectrum measurement, which is measured by the spectrometer, wherein the spectrometer is configured to measure spectra of all generated light that is generated from a time when the laser is projected onto the sample.

Abstract: The present disclosure relates to a method and a device for controlling a laser output. According to an embodiment, there are provided a method for controlling a laser output of a laser device, provided with a laser generator and a handpiece for radiating a laser generated at the laser generator onto a target, and a device performing the method. The method includes the steps of: measuring, by a plurality of distance sensors arranged along a circumference of one end of the handpiece from which the laser is outputted, distances between the plurality of distance sensors and the target; based on the distances between the distance sensors and the target, calculating an effective area which is a region of the target onto which the laser is really radiated; and increasing or reducing the laser output to radiate the laser onto the effective area with a predetermined energy density.

Abstract: According to one embodiment, a tip for a laser handpiece includes: a light radiating module configured to radiate a laser toward a target; and a light receiving module configured to receive at least a portion of light which is generated by the laser radiated onto the target as received light. The light radiating module includes: a base which has an inner space formed therein to allow the laser to pass therethrough; a fixing portion which is coupled to a lower portion of the base and has a penetrating hole formed therein to allow the laser to pass therethrough; and a module connecting member which is interposed and fixed between the base and the fixing portion.

Abstract: According to an embodiment of the present disclosure, a non-transitory computer readable storage medium which stores one or more non-discrete spectrum analysis programs for lesion tissue detection based on laser spectroscopy is provided. The one or more programs cause an electronic device provided with one or more processors to execute a lesion tissue detection method, and the lesion tissue detection method includes a step of determining whether there is lesion tissue by applying a lesion tissue detection learning model to a result of non-discrete spectrum measurement. The result of the non-discrete spectrum measurement is a result of measuring spectra of all generated light that is generated from a time when a laser is projected onto a sample until the generated light is no longer generated.
