Abstract: A method comprising at least one light source configured to generate a light of at least one wavelength and project the light over an optical path, a sample device, the device containing a sample obtained from exhalation of a person, a vortex mask configured to receive the light after the light passes through at least a portion of the sample device, the vortex mask including a series of concentric circles etched in a substrate, the vortex mask configured to provide destructive interference of coherent light received from the at least one light source, a detector configured to detect and measure wavelength intensities from the light in the optical path, the wavelength intensities being impacted by the light passing through the sample, the detector receiving the light that remained after passing through the vortex mask, and a processor configured to provide measurement results based on the wavelength intensities.

Abstract: A system comprising at least one light source configured to generate a light at specific wavelengths and project the light over an optical path, a sample device, the sample device configured to receive a sample obtained from a person, the sample device being transparent and being at least partially within the optical path, a diversifier including occlusions for scattering coherent light received from the light source along the optical path, a first detector configured to receive the light over the optical path and from at least a portion of the diversifier, the detector configured to detect spectral intensities of the light, and a second detector configured to receive at least a portion of the light form the optical path before the light passes through the diffuser, the second detector configured to detect spectral intensities of the light.
