Flaw Detection in Laser Powder Bed Fusion
Flaw detection and rapid fatigue fracture Additive manufacturing (AM) techniques have gained popularity in a number of high-value industries due to their capacity to produce small batches of geometrically ...
Optical Coherence Tomography: Introduction
If you’ve visited an optometrist, they may have used optical coherence tomography (OCT) to scan your retina. This new technique uses low coherence interferometry to image semi transparent tissue. Being a ...
Deformable Mirrors and “Fake” Stars in Space Photography
Why do We Need Deformable Mirrors? Deformable mirrors are specialty mirrors that are capable of deforming their reflective surface and thus achieve wavefront correction of optical aberrations. In astronomy ...
Cervical Cancer Diagnosis: New Minimally-Invasive Screening
Cervical cancer is a growth of abnormal cells on the surface of the cervix. The largest prevalence of this ailment is the so-called squamous cell carcinoma, that comprises approximately 70% of diagnosed ...
VCSEL Laser Technology: Applications in 3D Sensing and LiDAR
Ever wonder how facial recognition has come around to be implemented in smartphones today? Vertical cavity surface-emitting lasers, (abbreviated VCSEL, pronounced “vixel”) are to thank for such ...
Organic Transistors: Structure and Applications
Organic transistors are slowly taking over in the transistor space. Invented a few decades ago, they have been gaining more and more attention and proving themselves in such applications as flexible ...
Freeform Optics Design and Fabrication
Most are used to seeing lenses with very set radii of curvature. Typical lenses have surfaces that are plano, convex, concave, or any combination of those. Even in the cases of aspherical lenses or ...
Photonics Technologies in Aerospace and Defense Applications
One area where photonics is integrated prolifically is the aerospace and defense world. Giants of the aerospace and defense industry rely heavily on implementing photonics technologies to successfully ...
Metamaterial Applications Revisited: Optical and Acoustic
We have previously discussed metamaterials in an overview regarding their uses in lens design and optical cloaking, but the metamaterial realm stretches much further than that. Today, let us dive into ...
