Photons that are not collected or measured reduce the signal to noise and therefore reduce measurement precision. This invention collects the zero order light and sends it through the spectrometer again. In an atmospheric LIDAR, the zero order recycling is estimated to increase the rotational Raman signal by an additional 20%. A grating based spectrometer where the zero order light is collected by a lens or mirror and focused into a fiber optic that sends the light to the input slit where it is directed into the spectrometer again. There can be a plurality of recycle fibers. The detector can be either a single linear array or a two dimensional array such as a CCD or CMOS camera."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Spectrograph recycling","description":"Spectrographic measurements are often limited by the amount of light that is available.
