[Simultaneous and real-time collection by multi-fiber coupling and optical multi-channel analyzer].
A new kind of instrument and method for simultaneous and real-time collection of multi-object spectra by using multi-fiber coupling and Optical Multi-channel Analysis (OMA) was reported. The spectral signals of one object, three objects and five objects were collected successfully in experiments. The spatial resolution of 0.5 mm and detected spectral range of 200-1100 nm were reached, and at most twenty objects could be collected on the image plane of 1 cm2 area with OMA 4 system. The design of the coupling lens's light path was discussed to guarantee enough light energy to enter the instrument and little effect on the resolution of spectral instrument. The instrument can be applied widely to the areas of supervising and controlling the quality of light beam in transmission and in the time-resolved and spatial-resolved spectral measurement.
