Abstract

The invention discloses a wheel disc type light splitting test device, which comprises: a collimator used for receiving multi-wavelength input divergent light and converting the multi-wavelength inputdivergent light into parallel light; a filter mounting disc provided with a plurality of filter mounting holes, wherein filters with different wavelengths are mounted in the filter mounting holes, and the wavelengths of the filters are sequentially arranged from large to small or from small to large; a driving motor for driving the filter mounting disc to rotate; a detector used for receiving theemergent light filtered by the filters and testing; and an outer shell, wherein the collimator, the filter mounting disc, the driving motor and the detector are all mounted in the outer shell. According to the invention, the motor drives the filter mounting disc to rotate, the filters with different wavelengths are sequentially aligned with the light with different wavelengths input by the collimator for filtering operation, and the detector is sequentially used for detection while filtering, so that the purpose of light splitting test is achieved, and the technical requirements, the cost andthe size are reduced while the light loss is avoided.

Description

technical field [0001] The invention relates to the field of photoelectric communication, in particular to a wheel-disk type spectroscopic testing device. Background technique [0002] At present, CWDM / DWDM devices are mostly implemented by wavelength-by-wavelength filtering and AWG waveguide arrays. Wavelength-based step-by-step filtering causes optical loss due to step-by-step filtering, which affects detection; the manufacturing process of AWG waveguide array is complicated, the technical requirements are high, and the difficulty is great. Besides that, both approaches require the use of the same number of detectors as the number of wavelengths. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] The object of the present invention is to provide a wheel-disc type spectroscopic testing device to solve the problems raised in the above-mentioned background technology. [0005] In or...
