Abstract: A spectral imaging device (12) includes an image sensor (28), a tunable light source (14), an optical assembly (17), and a control system (30). The optical assembly (17) includes a first refractive element (24A) and a second refractive element (24B) that are spaced apart from one another by a first separation distance. The refractive elements (24A) (24B) have an element optical thickness and a Fourier space component of the optical frequency dependent transmittance function. Further, the element optical thickness of each refractive element (24A) (24B) and the first separation distance are set such that the Fourier space components of the optical frequency dependent transmittance function of each refractive element (24A) (24B) fall outside a Fourier space measurement passband.

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 laser assembly (10) for generating an assembly output beam (12) includes a laser subassembly (16) that emits a plurality of spaced apart laser beams (20), a beam adjuster (42), a transform lens (44A), a beam combiner (46), and an output coupler (48). The beam adjuster (42) adjusts the spacing between the plurality of laser beams (20). The transform lens (44A) focuses the laser beams (20) at a focal plane (54) and the beam combiner (46) is positioned at the focal plane (54). The beam combiner (46) combines the lasers beams (20) to provide a combination beam (58). Further, the output coupler (48) redirects at least a portion of the combination beam (58) back to the beam combiner (46) as a redirected beam (60), and transmits a portion of the combination beam (58) as the assembly output beam (12).

Abstract: A light source assembly includes a housing assembly and at least two sets of disparate light sources that are coupled to the housing assembly. The sets of disparate light sources include a first plurality of disparate light sources; and a second plurality of disparate light sources. Each plurality of disparate light sources includes a first light source that generates a first light beam having a first center wavelength and a second light source that generates a second light beam having a second center wavelength that is different than the first center wavelength. The first plurality of disparate light sources generates a first output beam that is directed along a first central beam axis. The second plurality of disparate light sources generates a second output beam that is directed along a second central beam axis that is spaced apart from the first central beam axis by at least approximately sixty degrees.

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: A laser source (340) that generates an output beam (354) that is directed along a beam axis (354A) that is coaxial with a first axis and orthogonal to a second axis comprises a first frame (356), a laser (358), and a first mounting assembly (360). The laser (358) generates the output beam (354) that is directed along the beam axis (354A). The first mounting assembly (360) couples the laser (358) to the first frame (356). The first mounting assembly (360) allows the laser (358) to expand and contract relative to the first frame (356) along the first axis and along the second axis, while maintaining alignment of the output beam (354) so the beam axis (354A) is substantially coaxial with the first axis. The first mounting assembly (360) can include a first fastener assembly (366) that couples the laser (358) to the first frame (356), and a first alignment assembly (368) that maintains alignment of the laser (358) along a first alignment axis (370) that is substantially parallel to the first axis.

Abstract: A body monitor (12) for monitoring a condition of a living being (10) includes (i) a monitor housing (28) that is positioned adjacent to the living being (10); (ii) a first laser source (240) that directs a first output beam (240A) at the living being (10) to generate first photoacoustic waves; (iii) a second laser source (242) that directs a second output beam (242A) at the living being (10) to generate second photoacoustic waves; and (iv) a photoacoustic detector (16) secured to the monitor housing (28). The photoacoustic detector (16) detects the first photoacoustic waves and the second photoacoustic waves to monitor the condition of the living being (10). The output beams (240A) (240B) have a different center wavelength and can be in the mid-infrared range.
