“…The basic components of UV-visible spectroscopy are identical to those used in infrared spectroscopy [21], with the exception of the interferometer, which is replaced by a monochromator in the UV-visible region. Monochromatic is an optical device that sends monochromatic bands of light from a light source to the sample [22]. Monochromator can either be based on filters, which selectively let through a narrow wavelength range, or on a dispersing element, which breaks up the radiation into its component waves so that a specific band can be chosen.in Figure .3.…”

In this paper, present a unique model of a comprehensive spectrograph Systems. the proposed optical system evaluates the performance of solid fuel columns SFC on the basis of spectroscopy, when they are fully combusted and exit the exhaust nozzle of a solid rocket fuel engine SRFE. By collecting and spectroscopic analysis of the radiation emitted by waste chemical compounds in the infrared, visible and ultraviolet ranges. The proposed spectroscopy system design features several optical systems specifically designed for performing spectroscopic measurements remotely. To take into account security and safety. The proposed optical system addresses many of the defects of the traditional systems used in this field. Such as not need to take a sample in a gas cell, like the case in the FTIR technique, and not to be affected by the surrounding environment from radioactive sources, like the case in the spectroscopy technique using visible and ultraviolet light radiation. There is a distinctive optical system for the thermal camera to prevent radiation sources resulting from existing reflections in the test environment, the synchronization time in fast cameras is 15 microseconds, which makes the 3D image formation algorithms work to create an ideal image, thus overcoming the defects of the digital inline holography system.

“…Polarizing elements increase dimensions, weight, and the cost of the optical system, and hamper the integration of off-the-shelf AOTFs into optical systems. In this regard, a polarizer-free AOTF design, previously demonstrated for non-imaging devices [ 23 ], seems especially attractive to be adapted for imaging applications. In this paper, we present an original biomedical SWIR imaging AOTF system, which minimizes aberrations.…”

Optical biomedical imaging in short wave infrared (SWIR) range within 0.9–1.7 μm is a rapidly developing technique. For this reason, there is an increasing interest in cost-effective and robust hardware for hyperspectral imaging data acquisition in this range. Tunable-filter-based solutions are of particular interest as they provide image processing flexibility and effectiveness in terms of collected data volume. Acousto-optical tunable filters (AOTFs) provide a unique set of features necessary for high-quality SWIR hyperspectral imaging. In this paper, we discuss a polarizer-free configuration of an imaging AOTF that provides a compact and easy-to-integrate design of the whole imager. We have carried out image quality analysis of this system, assembled it and validated its efficiency through multiple experiments. The developed system can be helpful in many hyperspectral applications including biomedical analyses.
