You need the right light source to see a hologram because it records the light's phase and amplitude like a code. Rather than recording a simple pattern of reflected light from a scene, it records the interference between the reference beam and the object beam. It does this as a pattern of tiny interference fringes. Each fringe can be smaller than one wavelength of the light used to create them. Decoding these interference fringes requires a key — that key is the right kind of light. Lehner, Markus; Mewes, Dieter (6 December 2012). Applied Optical Measurements. Springer.

Films can be made to record non- visible ultraviolet (UV) and infrared (IR) radiation. These films generally require special equipment; for example, most photographic lenses are made of glass and will therefore filter out most ultraviolet light. Instead, expensive lenses made of quartz must be used. Infrared films may be shot in standard cameras using an infrared band- or long-pass filters, although the infrared focal point must be compensated for. There are a couple of things to keep in mind about the object beam. One is that the object is not 100 percent reflective — it absorbs some of the laser light that reaches it, changing the intensity of the object wave. The darker portions of the object absorb more light, and the lighter portions absorb less light. A photograph can be recorded using normal light sources (sunlight or electric lighting) whereas a laser is required to record a hologram. Basic Sensitometry and Characteristics of Film" (PDF).

Retrieved 8 August 2015.One method of mass-producing holograms is coating this surface in metal to strengthen it, then using it to stamp the interference pattern into metallic foil. A lot of the time, you can view these holograms in normal white light. You can also mass-produce holograms by printing them from a master hologram, similar to the way you can create lots of photographic prints from the same negative. Conventional HUDs project the information only with the help of the bare windshield’s reflectivity into the driver’s eyes. The given reflectivity of the windshield however limits the brightness of the image and in addition the size of the image at a given space for the projection unit in the dashboard. The couplers need to be made resistant to diffusion (non-diffusible) so that they will not move between the layers of the film [13] and thus cause incorrect color rendition as the couplers are specific to either cyan, magenta or yellow colors. This is done by making couplers with a ballast group such as a lipophilic group (oil-protected) and applying them in oil droplets to the film, or a hydrophilic group, or in a polymer layer such as a loadable latex layer with oil-protected couplers, in which case they are considered to be polymer-protected.

The developed hologram's surface consists of a very fine, seemingly random pattern, which appears to bear no relationship to the scene it recorded. LitiHolo film is a special material called a holographic photopolymer, that is uniquely suited for making holograms instantly! As the film is exposed, it deveops at the same time. When the exposure is complete, the active materials in the film have been used up, and the hologram can be viewed immediately without waiting. SimpleGraham, Marty. "Fake Holograms a 3-D Crime Wave."

No wet chemicals, no mess, no cleanup, and did we mention no chemicals! You can make holograms right at home or in standard classroom. Full-Color Sensitive For a better understanding of the process, it is necessary to understand interference and diffraction. Interference occurs when one or more wavefronts are superimposed. Diffraction occurs when a wavefront encounters an object. The process of producing a holographic reconstruction is explained below purely in terms of interference and diffraction. It is somewhat simplified but is accurate enough to give an understanding of how the holographic process works. Langford, Michael (2010).
