By using high-quality optical filters in the excitation and detection paths, the trade-off between spectral information and ultimate sensitivity is controlled by the choice of filter edge locations and bandwidths. An initial implementation of this approach, using a 405nm diode laser as an ...
Interference filters are provided on all but one of the sides and angled spacers are provided to connect optically the filters with collimating lenses. In the case of the side without a filter a spacer connects that side directly with a collimating lens. Optical fibers are joined optically to ...
Design and manufacturing of optical filters based on interference optical filters for IR, UV and visible areas of spectra; Design and manufacturing of special optical filters for analysis of air contaminants; Design and manufacture of various optical components, such as: lenses, prisms, mirrors and ...
We introduce an axial localization with repetitive optical selective exposure (ROSE-Z) method for super-resolution imaging. By using an asymmetric optical scheme to generate interference fringes, a <2 nm axial localization precision was achieved wi
Using optical interference coatings to create colours results in colours that are dependent on the observation angle. We have introduced a new parameter for quantification of angular colour dependence. Our results show that the angular colour dependence can be reduced by increasing the refractive indices...
Communication using the optical fibre channel can be challenging due to nonlinear effects that arise in the optical propagation. These effects represent physical processes that originate from light propagation in optical fibres. To obtain fundamental und
20.7 kHz. All image reconstruction and analyses were performed with Matlab (Mathworks) using raw data from the spectrometer. The first lens of the imaging system (LSM03-BB, Thorlabs) provides a lateral resolution of 8 mm (full-width at half-maximum, FWHM) and depth of field of 143 mm in...
We implemented the proposed and comparison methods in MATLAB R2016b. The largest computational cost of the proposed method comes from the extraction of the dominant AM target signature from the modulation domain. To reduce the computational cost during experimentation, we first acquire the dominant AM...
A receiver filter filters the received electrical data signal. The receiver filter has a transfer function that reduces adjacent symbol interference in the received electrical data signal.doi:US20020167703 A1Merritt, Scott AndrewUSUS20020167703 2001年5月3日 2002年11月14日 Merritt Scott Andrew Tandem ...
Molecular mechanisms of PMN trans-epithelial migration have been well characterized using the polarized T84 intestinal epithelial cell line grown inverted on permeable Transwell filters2,16. Various forms of microscopic imaging have been utilized to observe immune cells in action to gain a better ...
