ONLINE SPECTRUM ANALYZER FOR DETECTING DIFFUSE REFLECTION WITH ULTRAVIOLET (UV), VISIBLE AND NEAR INFRARED (NIR) LIGHT

摘要

An online spectrum analyzer for detecting diffuse reflection with UV, visible and NIR light includes a housing, inside which an illuminating system, a probe, an optical splitting system, a signal acquiring system, a calibrating system and a spectrum processing system are provided. The illuminating system, the signal acquiring system, the calibrating system and the spectrum processing system are all together connected to a power supply system. The illuminating system is used to emit the light rays of UV, visible and NIR waveband to illuminate the detected object. The probe is used to collect the light rays diffuse-reflected by the detected object, and transmit the collected light rays to the optical splitting system. The light rays are split by a grating to form light rays with different wavebands. The signal acquiring system converts the optical signal into digital signal and collects the digital signal. The spectrum calibrated by the calibrating system is sent to the spectrum processing system to be processed, analyzed and displayed so that the detection result is determined.
