In recent years, diffractive optical elements (DOEs) have become increasingly popular in multispectral imaging applications. This is due to their ability to provide superior image quality, lower cost, and enhanced spectroscopic capabilities. In this article, we take a snapshot of the current state of multispectral imaging with diffractive optical elements.

Diffractive optical elements have the unique ability to manipulate the wavelength of light in order to produce a desired image. This is done by diffracting the incident light onto a patterned surface. The light is then scattered in a wide range of wavelengths, allowing for the capture of multiple images in different spectral ranges. This allows for the capture of more detailed images than those produced with conventional lenses.

Another advantage of diffractive optical elements is their cost-effectiveness. Due to their simple design, they are typically much cheaper to produce than conventional lenses. Furthermore, they are highly durable, making them ideal for applications where long-term performance is required.

Finally, diffractive optical elements offer enhanced spectroscopic capabilities. This allows for the capture of multiple images in different spectral ranges, providing a richer and more detailed image. This is especially useful for applications such as medical imaging, where
