Acousto-optic devices represented by acousto-optic tunable filters (AOTFs), have the advantages of wide wavelength range from the ultraviolet to the long-wave infrared and fast wavelength switching speed. Nowadays, acousto-optic spectral systems have become very important scientific instruments in laboratory. There are many factors to be considered when we choose different solutions for acousto-optic spectral systems, but there is no comprehensive analysis and summary of them. This paper explains the working principle of the acousto-optic devices and summarizes the most common optical schemes for acousto-optic spectral systems. We also analyzed their characteristics of application conditions. In addition, specific applications of acousto-optic spectral systems in some common fields are presented.

“…In contrast, the total reflection system has the advantages of no chromatic aberration, easy miniaturization, lightweight, and can better meet the needs of the deep space field. Then, the total reflection optical system of broadband and integrated AOTF imaging spectrometer (0.4-5.0 μm) was designed by L. Chang and Q. Zhang [15] . They adopted one of the optical design schemes of the AOTF imaging spectrometer, namely the collimation scheme.…”

Compressive spectral imaging (CSI) is an advanced computational imaging approach to reconstruct the three-dimensional (3D) spatio-spectral data cube of a target scene through a single or a few snapshots. However, limited by the response range of the image detector, the existing CSI systems mostly work within narrow spectral bands, such as the visible or shortwave-infrared (SWIR) spectral band. The work band of the CSI system constrains the detection capacity for the targets under complex environments (such as rain, snow, haze, etc.). In addition, most of the current CSI prototypes lack engineering design for practical applications. This paper develops a novel, to the best of our knowledge, optical design scheme of a broadband CSI system with co-aperture coding to simultaneously realize visible multi-spectral imaging (10 channels) and SWIR super-resolution imaging (16×). The freeform surfaces are used to design the front-end reflective objective lens, thus significantly improving the image quality and spatial modulation precision of the system. By means of performance evaluation and tolerance analysis, excellent image quality and manufacturability of the proposed system are demonstrated.
