Abstract
Disclosed is optical observation equipment for identifying the forming process of a malignant tumor, which is provided with a receiving space and a transparent front end. The optical observation equipment comprises: a light-guide fiber, a laser emitter, a focusing device, a white light emitter, an image sensor, a high gain amplifier and an encoding and emitting device, wherein the light-guide fiber extends to the transparent front end from the receiving space; the laser emitter emits laser with a wavelength of 340 nm±20 nm and an energy of 0.3˜0.5 mj/m2 in a pulsing mode; the focusing device is coupled to the output end of the laser emitter and used for focusing the laser to the input end of the light-guide fiber; the white light emitter is used for emitting white light, and the white light is guided into the input end of the light-guide fiber, wherein the laser emitter and the white light emitter are alternately turned on; the image sensor is used for acquiring an image of an area irradiated by light emitted from the output end of the light-guide fiber and converting a light signal into an electric signal; the high gain amplifier is coupled to the image sensor and is used for ampl…
