We&#8217;re calling it &#8220;Make a Hologram Monday&#8221; (and yes, it is Tuesday today, but our Monday project extended over a little bit!).

Look for that soon.<\/p>\n\n\n\n<p>But now let&#8217;s get back to making some holograms!  A handful of dice, some holographic parallax, and suddenly you have the makings of an overt authentication feature sometimes called an Optically Variable Device, but more commonly called&#8230; a hologram.<\/p>\n\n\n\n<!--more-->\n\n\n\n<p>The video of the final hologram is at the end, and it&#8217;s pretty sweet being able to &#8220;look around&#8221; inside the hologram and see all the different sides of the dice!

A few set up tips to help get things looking good:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>The hologram film plate needs to rest in a stable position on top of the dice.  If it is wobbly or has any movement, it will make your hologram dim.<\/li><li>Place a blank glass plate of the same size (included in kit) on top and turn off other lights in the room so that you can only see the laser light.  This gives you a good visual indicator of the &#8220;window&#8221; area that the hologram is capturing.  If you can&#8217;t see part of the objects under just the laser light, it probably won&#8217;t show up in your hologram either.<\/li><li>Use the white card (also in the kit) and place it on top of the glass plate to check how evenly the laser light is illuminating the glass plate.  Only the part of the card that is illuminated by the laser AND gets laser light reflected from the objects will for a hologram.<\/li><\/ul>\n\n\n\n<p>Once everything looks good, it&#8217;s time to expose the hologram.  Place the shutter in front of the laser to block the laser light, get out a fresh hologram film plate placing it on top of the dice in a stable position, and remove the shutter to begin the exposure.  We used an exposure time of about 4 minutes.<\/p>\n\n\n\n<p>One of the amazing and fun things about the <a href=\"https:\/\/www.litiholo.com\/hologram-film.html\">LitiHolo self-developing hologram film<\/a>, is that the hologram is forming and developing as the exposure takes place.  Once the exposure is done (film is saturated), the hologram is done, and ready to be viewed immediately.  After the exposure is done, you can slowly pick it up and you will see the hologram image from the plate mixing with the image of the objects, like you just removed a clone of the scene.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hologram parallax and security<\/h2>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Monday - Make a Hologram - Dice, Parallax and Security Features\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/YqHn4kaECTA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>Watch the center die!  As the hologram is moved around, you can see the top, left, bottom, and then right sides, and read the numbers on each face.  This ability to &#8220;look around&#8221; the object is called parallax, defined as:<\/p>\n\n\n\n<p>\n\npar\u00b7al\u00b7lax\/\u02c8per\u0259\u02cclaks\/<a href=\"https:\/\/www.google.com\/search?sca_esv=1b6c1bc5b84c8566&amp;sxsrf=ADLYWIKH1EczRi9wozC0_b6b2MPmq_X0Gg:1717502407755&amp;q=how+to+pronounce+parallax&amp;stick=H4sIAAAAAAAAAOMIfcRoxS3w8sc9YSnDSWtOXmPU5uINKMrPK81LzkwsyczPExLhYglJLcoV4pHi4uIoSCxKzMlJrLBiUWJKzeNZxCqZkV-uUJKvUADUkw_UlKoAUwIAFVpi7FsAAAA&amp;pron_lang=en&amp;pron_country=us&amp;sa=X&amp;sqi=2&amp;ved=2ahUKEwiB5aiH88GGAxWuMVkFHQdsCQcQ3eEDegQIJhAM\"><\/a><em>noun<\/em><\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>The effect\u00a0whereby\u00a0the position or direction of an object appears to differ when viewed from different positions<\/li><\/ol>\n\n\n\n<p>Parallax in holograms is often used as an overt security feature on tags and labels to indicate an item&#8217;s authenticity.  While detecting a knock-off of a branded item or collectible might be difficult just by looking at the item itself, the hologram with its unique parallax features is easy to identify and adds an extra layer of difficulty for forgers.  Security holograms have been used in this manner by companies like Visa and Mastercard to protect credit cards, Intel and AMD to authenticate microprocessors, and Nike to prevent forgeries of branded merchandise.<\/p>\n\n\n\n<p>Holograms like the one in this example are simple, and would not fool anyone as a security feature, but it is a great way to understand the principles of holograms, parallax, and how how holograms are being used as security features.<\/p>\n\n\n\n<p>If you&#8217;d like to experiment with holograms more, and make some of your own, take a look at our <a href=\"https:\/\/www.litiholo.com\/hologram-kits.html\">Hologram Kits<\/a>, <a href=\"https:\/\/www.litiholo.com\/hologram-upgrade-kits.html\">Upgrade Kits<\/a>, and our <a href=\"https:\/\/www.litiholo.com\/hologram-film.html\">self-developing Hologram Film<\/a>.<\/p>\n\n\n\n<p>&#8211; LitiHolo<\/p>\n","protected":false},"excerpt":{"rendered":"<p>As part of trying to push past our massive office flood at the end of last year, and trying to restart operations with our latest &#8220;Reserve a Hologram&#8221; process, we thought we&#8217;d have a little fun too.
