Industry Introduction

What is the purpose of beam splitting in the production process of Holographic Laser Film?

Beam splitting is a crucial step in the production process of holographic laser film, serving several essential purposes:

Creating Reference and Object Beams: Beam splitting allows a single laser beam to be divided into two separate beams: the reference beam and the object beam. These two beams play distinct roles in the holography process.

Interference Pattern Formation: The reference beam and object beam are directed onto the same recording medium from different angles. When they intersect on the recording medium's surface, they create an interference pattern. This interference pattern encodes the spatial information of the subject being recorded.

Hologram Formation: The interference pattern formed by the reference and object beams is the essence of holography. It represents the variations in light intensity and phase caused by the interaction of the object with the object beam. This pattern is recorded on the holographic recording medium and serves as the hologram itself.

Reconstruction: During playback or viewing of the hologram, the reference beam is directed onto the recorded interference pattern. When it interacts with the hologram, it reconstructs the original object beam, effectively recreating the three-dimensional image of the subject. The interference pattern allows for the recreation of the object's appearance from various angles.

Depth and Three-Dimensional Information: By having both a reference beam and an object beam, holography captures not only the surface information of the subject but also the depth and three-dimensional characteristics. This is in contrast to conventional photography, which captures only surface appearances.

Phase Information: The interference pattern formed by the reference and object beams also encodes phase information about the light waves scattered or diffracted by the subject. This phase information contributes to the hologram's ability to reproduce a coherent and realistic 3D image.

What is the principle of color change of Holographic Laser Film?

The color change effect in holographic laser film is a result of the interference of light waves and is based on the principles of interference and diffraction. Here's how the color change effect in holographic laser film works:

Interference of Light Waves: Holographic laser film is produced using a process called holography, which involves recording the interference pattern created by two laser beams: the reference beam and the object beam. When these beams overlap and interact on a photosensitive recording medium, they create a complex pattern of bright and dark areas due to constructive and destructive interference of light waves.

Periodic Variation: The interference pattern recorded on the holographic film consists of microscopic variations in the thickness or refractive index of the film. These variations occur at a microscopic scale, with a periodic pattern determined by the spacing of the interference fringes.

Diffraction Grating: The recorded interference pattern essentially forms a diffraction grating on the holographic film. A diffraction grating is a device that disperses light into its component colors, similar to a prism but with a more controlled and periodic structure.

Angle-Dependent Color Change: When white light or a white light source, such as sunlight or a lamp, is directed onto the holographic laser film, the diffraction grating effect comes into play. As the angle of view or illumination changes, different colors are diffracted and observed by the viewer. This angle-dependent color change is a result of the varying wavelengths of light being dispersed at different angles due to the diffraction grating.

Iridescence: The color change effect in holographic laser film is often described as iridescence. Iridescence refers to the phenomenon where colors appear to shift and change as the angle of view or illumination changes. The specific colors observed can vary depending on the design and properties of the holographic film.

Thin-Film Interference: The color change effect is also related to thin-film interference. The periodic variations in the holographic film's thickness or refractive index create multiple layers with different optical properties. As light passes through these layers and reflects from them, interference between the light waves occurs, leading to the observed color shifts.

Controlled Design: The design and construction of the holographic film, including the spacing and arrangement of the interference fringes, can be customized to achieve specific color patterns and effects. This level of control allows for the creation of holographic laser film with unique and visually striking color-change characteristics.
