The aberrations of reflective optical systems with one plane of symmetry are investigated in the most general case, with freeform surfaces and possibly different locations of the tangential and sagittal object and image. In this first paper in a series of two, we establish generalized ray-tracing equations including transverse aberrations up to...

The aberrations of reflective optical systems with planar symmetry are investigated in the most general case, with freeform surfaces and possibly different locations of the tangential and sagittal object and image. In this second and last paper, closed-form expressions are derived for the aberrations created by an individual mirror. We study two...

Quantum computers (QC) promise to solve certain computational problems exponentially faster than a classical computer due to the superposition and entanglement properties of quantum bits (qubits). Among several qubit technologies, spin qubits are a promising candidate for large-scale QC, since (1) they have a small footprint allowing them to be...

In this paper, we report the effect of optical trapping on the enhancement factor for Raman spectroscopy, using a dielectric metasurface. It was found that a higher enhancement factor (up to 275%) can be obtained in a substrate immersed in water, where particles are freee to move, compared to a dried substrate, where the particles (radius r = 9...

TNO heeft een van de eerste volwaardige 5g-testnetwerken in Europa gelanceerd. Het netwerk opereert in de 3,5 GHz-band via een officiële Nederlandse testlicentie en maakt het mogelijk om geavanceerde toepassingen zoals ar/vr, supersnelle videoverbindingen, zelfrijdende auto’s en drones voor industriële toepassingen te testen. Het publiek-private...

Time difference of arrival geolocation is re-analysed exploiting all available time differences, though sticking to closed-form algorithms based on the minimum number of time differences. The additional information is statistically utilised in a sound way. Error estimates for the resulting position and the Cramer-Rao lower bound are derived. The...

While Atomic Force Microscopy is mostly used to investigate surface properties, people have almost since its invention sought to apply its high resolution capability to image also structures buried within samples. One of the earliest techniques for this was based on using ultrasound excitations to visualize local differences in effective tip...

We study a containment control problem (CCP) and a shape control problem (SCP) for systems whose initial condition is a random variable with known distribution. The two control problems both require exponential convergence to a desired trajectory, which is complemented by either; (i) a required cumulative distribution over a prescribed...

We designed and built a compact bi-axial electron beam separator. This separator is an indispensable electron optical element in the development of MEMS-mirror-based miniaturized concepts for quantum electron microscopy (QEM) and aberration-corrected low-voltage scanning electron microscopy (AC-SEM). The separator provides the essential cycling...

Method of depositing an atomic layer on a substrate. the method comprises supplying a precursor gas fraom a precursor-gas supply of a deposition head that may be part of a rotatable drum. The precursor gas is provided from the presursor-gas supply towards the substrate. The method further comprises moving the precursor-gas supply by rotating the...

We combine a low dark current and high-detectivity near-infrared (NIR)-sensitive organic photodetector with a high-resolution 508 pixels per inch (ppi) oxide thin-film transistor (TFT) backplane to create a large-area thin NIR detector, using processes that are compatible with flat-panel display fabrication. The detector is characterized showing...

The real-time and accurate measurement of tip-sample interaction forces in Tapping Mode Atomic Force Microscopy (TM-AFM) is a remaining challenge. This obstruction fundamentally stems from the causality of the physical systems. Since the input of the dynamic systems propagates to the output with some delay, and multiple different inputs can...
