There is described a method for detecting a given gas species present in a gaseous sample. The method generally has splitting a primary optical pulse into first and second optical pulses, the primary optical pulse having a duration and carrying optical power within an excitation spectrum encompassing at least one absorption spectral band of the given gas species, the first optical pulse being propagated across an optical gas filter unit containing an amount of the given gas species and attenuating the first optical pulse at the at least one absorption band, one of i) the primary optical pulse and ii) the first and second optical pulses being propagated across the gaseous sample, and temporally delaying the first and second optical pulses from one another; measuring signal values of the delayed optical pulses; and detecting the presence of the given gas species in the gaseous sample based on the signal values.

In acquisition of spatial transcriptomic information, a plurality of images representing a common field of view of a sample are obtained and registered. Each pixel of the registered images is decoded by identifying a code word from a plurality of code words in a code book that provides a best match to data values in the plurality of registered images for the pixel. For each code word identified as a best match and each pixel, whether a bit ratio for an image word for the pixel meets a threshold for the code word is determined. The image word is formed from the data values in the plurality of registered images for the pixel. For at least one pixel that is determined to meet the threshold, a gene associated with the code word is determined. Pixels for which the bit ratio does not meet the threshold are screened.
