Abstract : Nearly time independent measurements of low-absorption coefficients of atmospheric constituents can be made with long-path absorption cells by obtaining short-term averages of transmittance values related to cell mirror reflectivity through rapid changes in the cell pathlength between short and long multipaths. The invention described herein may be manufactured and used by or for the Government for governmental purposes without the payment of any royalties thereon or therefor. (Author)
