“…In this way, desirable color holographic display can be achieved by adjusting the intensity of three color images. In 2019, an optical aperture and digital lenses based on the LC‐SLM were used in the optical zoom system, and the image can be displayed on the receiving screen without high‐order diffraction light and high‐order diffraction images . Besides, the attenuators based on the LC can be used to control the intensity of the holographic reconstruction.…”

Holographic display technology can reconstruct the same images of the original objects exactly, which has played a more and more important role and become the goal of the three‐dimensional display. As liquid crystal devices can modulate the polarization state of light, they have been widely used in the holographic display to modulate the phase and amplitude of information. Among them, liquid crystal spatial light modulator and liquid crystal lens are two important devices in the holographic diffraction. In this paper, several liquid crystal devices have been introduced and the holographic display technologies based on these liquid crystal devices have been discussed. The merits and demerits of these technologies based on the liquid crystal devices have been analyzed, and the outlook of the holographic display is given in the end.

This paper presents the design, manufacturing, and characterization of a three-dimensional (3D)-printed and electromagnetically actuated adjustable optical slit structure. The device comprises magnet-attached slits connected to the main frame via two springs controlled by external coils. To analyze the forces acting on the springs and simulate the mechanical behavior of the device, we developed both analytical and finite-element models. After fabricating the device using fused deposition, we conducted a series of tests to evaluate its performance. These tests included (1) analyzing the opacity of the slit blade as a function of its thickness, (2) measuring the temperature increase resulting from the power applied to the coils to determine the operable range of the structure, and (3) evaluating the hysteresis, repeatability, and resolution (minimum step) of the device. The experimental works were crucial to assessing the device’s practicality and optimizing its performance for specific applications, which reveals a maximum slit width of ∼450µm, with ∼6.4µm step size within this study. Overall, our developed slit device has the potential to be useful in various optics-related laboratories due to its compatibility with conventional 1-inch (25.4 mm) diameter optomechanical mounts, compact form, low power consumption, and rapid prototyping capability with hybrid materials in a cost-friendly fashion, owing to the 3D-printing technology. We discuss an application where the adjustable slit is employed in a combined laser-scanning microscope and a spectrometer, highlighting its versatility and potential for the future.
