Honeywell has unveiled the development of a new technology, Digital Holographic Microscopy (DHM), which uses artificial intelligence (AI) to count and classify microscopic particles or cells efficiently. This innovation holds significant potential across various industries where rapid analysis and streamlined operations are essential.

At the recent High Security Printing™ (HSP) EMEA conference in Basel (3-5 February), Georgios Tziovaras, Global Business Development Manager at Covestro Specialty Films, highlighted the crucial role of holography and advanced optical technologies in modern identity documents.

Researchers from EPFL’s Laboratory of Applied Photonic Devices, led by Christophe Moser, in collaboration with Jesper Glückstad’s team at the University of Southern Denmark (SDU), have revealed a breakthrough in 3D printing.

In the January and February 2025 issues of Holography & Optical Technology News™, we covered banknotes featuring optical innovations from Argentina, Mauritius, Romania, Kazakhstan, the Philippines, Kenya, China, the Falklands, and Belize.

Recent advancements in nanofabrication have demonstrated new possibilities for enhancing the design of optical security devices (OSDs) that display different images under various lighting conditions, including those combining colour printing with holography. However, the complexity of designing such devices and the challenge of scaling them up for real-world use remain significant hurdles.

Researchers from the Institute of Electronic Structure and Laser, Foundation for Research and Technology Hellas and the University of Crete, both in Greece, have developed a groundbreaking optical encryption method that they claim achieves an outstanding level of security.

The Chinese Lunar New Year 2025 began on 29 January, marking the start of the Year of the Snake. While people and organisations celebrate this in various ways, Holography & Optical Technology News® focuses on a few innovative industry developments welcoming the year of the snake.

A European research team from Germany, the Czech Republic, and Belgium is developing an innovative imaging technology to visualise neuronal processes in living organisms with high precision.

CES® (short for the Consumer Electronics Show) is justifiably referred to as the most influential technology event in the world. It is the proving ground for breakthrough technologies and global innovators. CES 2025 was held at the Las Vegas Convention Center from 7-10 January 2025.

Advances in optical security technologies are crucial in combating counterfeiting, particularly for government issued documents and banknotes. A recent development in this field is the creation of a high-numerical-aperture (NA) multilevel diffractive microlens array (MLA) that operates across multiple wavelengths.
