Field: Measurement (Instruments)
Classification: CPC A  G | IPC A  G

Claim 12:
13. A method comprising:
generating, by at least one light source, a light of at least one wavelength and project the light over an optical path;
receiving, by a sample device, the light from the at least one optical source, the device containing a sample obtained from exhalation of a person, the sample device being transparent and being at least partially within the optical path;
providing destructive interference of coherent light passed through the sample device using a vortex mask, the vortex mask including a series of concentric circles etched in a substrate;
measuring, by a detector, wavelength intensities of the light after having passed through the vortex mask; and
providing measurement results based on wavelength intensities.
