Wearable optical fiber probe

Abstract

The invention discloses a wearable optical fiber probe. The wearable optical fiber probe comprises a housing, the housing is internally provided with a laser channel and a Raman scattering collection channel, the laser channel and the Raman scattering collection channel are mutually parallel, the wearable optical fiber probe further comprises a detection channel, the laser channel is connected with the detection channel through an optical filter; an incident optical fiber, a first collimating lens and the optical filter are sequentially arranged in the laser channel in the spreading direction of the incident laser; a second collimating lens, a detection optical fiber and a self-focusing lens are sequentially arranged in the detection channel in the spreading direction of the reflection laser obtained after the incident laser is reflected by the optical filter; the optical filter, a third collimating lens and a collection optical fiber are sequentially arranged in the Raman scattering collection channel along the Raman reflection direction of the reflection laser. The self-focusing lens is used as the collection lens, a light source is guaranteed to be converged to the surface of a detected object, the fact that no gap exists between the probe and the detected object is guaranteed, a signal in the environment is prevented from entering the probe; moreover, the focusing position is not affected by the degree of tightness and the motion of a wrist strap and the like, so that the spectral information is guaranteed to be accurately collected.
