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 assembly (12) for rapid thermal data acquisition of a sample (10) includes a laser source (14), a light sensing device (26), and a control system (28). The laser source (14) emits a laser beam (16) that is directed at the sample (10), the laser beam (16) including a plurality of pulses (233). The light sensing device (26) senses mid-infrared light from the sample (10), the light sensing device (26) including a pixel array (348). The control system (28) controls the light sensing device (26) to capture a plurality of sequential readouts (402) from the pixel array (348) with a substantially steady periodic readout acquisition rate 405. The control system (28) can generate a spectral cube (13) using information from the readouts (402).

Abstract: A spectral imaging device (12) for generating an image (13A) of a sample (10) includes (i) an image sensor (30); (ii) a tunable light source (14) that generates an illumination beam (16) that is directed at the sample (10); (iii) an optical assembly (22) that collects light from the sample (10) and forms an image of the sample (10) on the image sensor (30); and (iv) a control system (32) that controls the tunable light source (14) and the image sensor (30). During a time segment, the control system (32) (i) controls the tunable light source (14) so that the illumination beam (16) has a center wavenumber that is modulated through a first target wavenumber with a first modulation rate; and (ii) controls the image sensor (30) to capture at least one first image at a first frame rate. Further, the first modulation rate is equal to or greater than the first frame rate.

Abstract: An assembly (10) for generating a laser beam (12) includes a beam steering assembly (18); a laser assembly (16) that is tunable over a tunable range; and a controller (20). The laser assembly (16) generates a laser beam (12) that is directed at the beam steering assembly (18). The controller (20) dynamically controls the beam steering assembly (18) to dynamically steer the laser beam (12) as the laser assembly (16) is tuned over at least a portion of the tunable range. As a result thereof, the laser beam (12) is actively steered along a desired beam path (12A) while the wavelength of the laser beam (12) is varied.
