Systems and methods disclosed herein provide for detecting gas by: illuminating, with a controllable illuminator system, a scene with light including radiation within the infrared (IR) wavelength range; controlling the illuminator system to emit light at a first wavelength corresponding to a first absorption level of a gas and at a second wavelength corresponding to a second absorption level of a gas, such that an equal amount of radiant energy over a time period is emitted onto the scene for each of said first and second wavelengths; and capturing a first IR image of the scene being illuminated with light at said first wavelength and a second IR image of the scene illuminated with light at said second wavelength, and comparing said first and second IR images to determine whether a characteristic for at least one specific gas is represented in said first and/or second IR images.

An optoelectronic device may include an arrangement having a plurality of emitter elements configured to sequentially emit light of different wavelength ranges. The arrangement may include a plurality of time-of-flight detector elements configured to detect the light emitted by the emitter elements and reflected at a sample and to carry out a measurement for determining the distance of the reflection point of the light at the sample from the respective time-of-flight detector element. The device further includes an evaluation unit configured to generate a three-dimensional image of the sample for each wavelength range emitted by the emitter elements on the basis of the light detected by the time-of-flight detector elements and the distance of the reflection point of the light from the respective time-of-flight detector element and to determine the distribution of a substance in the sample from the images.

A method of determining the concentration of an analyte in a sample of a body fluid with a mobile device having a camera is disclosed. The camera captures an image of a color reference card and of a reagent test field of an optical test strip having a sample applied to it. A predetermined pixel-based mean tone map correction is applied to the image obtained, which results in a first intensity-corrected image. Local brightness information is derived from the first intensity-corrected image. A mobile device-specific tone map correction is applied to the first intensity-corrected image, taking into account the local brightness information. A second intensity-corrected image is thereby obtained. Analyte concentration is determined based on a color formation reaction of the test field by using the second intensity-corrected image. Optionally, a color correction may be derived and applied to the second intensity-corrected image to obtain an intensity-corrected and color-corrected image.

Identifying blood formed elements within the blood sample may include identifying a type and amount of white blood cells, and/or identifying an amount of red blood cells and/or hematocrit, and/or identifying an amount of platelets. Identifying blood formed elements within the blood sample may include determining numbers and percentage by volume in the blood sample of one or more types of white blood cells.
