    Abstract: An assembly (14) for analyzing a sample (15) includes a detector assembly (18); a tunable laser assembly (10); and (iii) a laser controller (10F). The detector assembly (18) has a linear response range (232) with an upper bound (232A) and a lower bound (232B). The tunable laser assembly (10) is tunable over a tunable range, and includes a gain medium (10B) that generates an illumination beam (12) that is directed at the detector assembly (18). The laser controller (10F) dynamically adjusts a laser drive to the gain medium (10B) so that the illumination beam (12) has a substantially constant optical power at the detector assembly (18) while the tunable laser assembly (10) is tuned over at least a portion of the tunable range.

    Abstract: A spectral imaging device (1312) for capturing one or more, two-dimensional, spectral images (1313A) of a sample (1310) including (i) an image sensor (1328), (ii) an illumination source (1314), (iii) a beam path adjuster (1362), and (iv) a control system (1330). The illumination source (1314) that generates an illumination beam (1316) that is directed along an incident sample beam path (1360) at the sample (1310). The beam path adjuster (1362) selectively adjusts the incident sample beam path (1360). The control system (1330) controls (i) the illumination source (1314) to generate the illumination beam during the first capture time, (ii) the image sensor (1328) during the first capture time to capture first information for the first spectral image (1313A), and (iii) the beam path adjuster (1362) to selectively adjust the incident sample beam path (1360) relative to the sample (1310) during the first capture time while the image sensor (1328) is accumulating the information for the first spectral image (1313A).

    Abstract: An analysis assembly (12) for analyzing one or more physiological parameters of a person (10) comprises a sensor assembly (14) and an analyzer (16). The sensor assembly (14) includes a sampler (218) that collects a sample (220) from the person (10); and a signal generating apparatus (222) that directs a mid-infrared light beam (232) toward the sample (220) and performs spectroscopy on the sample (220) to generate a signal (215) that is based at least in part on the one or more physiological parameters of the person (10). The sampler (218) and the signal generating apparatus (222) can be positioned less than approximately one meter from the person (10) while the sample (220) is being collected and spectroscopically scanned to generate the signal (215). The analyzer (16) receives and analyzes the signal (215) to determine the presence of the one or more physiological parameters in the sample (220).

    Abstract: A spectral imaging device (12) includes an image sensor (28), an illumination source (14), a refractive, optical element (24A), a mover assembly (24C) (29), and a control system (30). The image sensor (28) acquires data to construct a two-dimensional spectral image (13A) during a data acquisition time (346). The illumination source (14) generates an illumination beam (16) that illuminates the sample (10) to create a modified beam (16I) that follows a beam path (16B) from the sample (10) to the image sensor (28). During the data acquisition time (346), the control system (30) controls the illumination source (14) to generate the illumination beam (16), and controls the image sensor (28) to capture the data. Further, during the data acquisition time (346), an effective optical path segment (45) of the beam path (16B) is modulated.
