Non-contact, automated cardiac pulse measurements using video imaging and blind source separation

Optics Express, Vol. 18 Issue 10, pp.10762-10774 (2010)
Poh, Ming-Zher; McDuff, Daniel J; Picard, Rosalind W
Remote measurements of the cardiac pulse can provide comfortable physiological assessment without electrodes. However, attempts so far are non-automated, susceptible to motion...

A compact bi-wavelength polarization splitting grating coupler fabricated in a 220 nm SOI platform

Optics Express, Vol. 21 Issue 25, pp.31019-31028 (2013)
Streshinsky, Matthew; Shi, Ruizhi; Novack, Ari; Cher, Roger Tern Poh; Lim, Andy Eu-Jin; Lo, Patrick Guo-Qiang; Baehr-Jones, Tom; Hochberg, Michael
We experimentally demonstrate a polarization splitting grating coupler that is operational near 1310 nm and 1550 nm in a silicon-on-insulator platform, using the same fiber angle for...

Numerical far field simulations with the fast Fourier transformation and Fourier space interpolation

Optics Express, Vol. 23 Issue 3, pp.3341-3352 (2015)
Lorbeer, Raoul-Amadeus; Meyer, Heiko; Ripken, Tammo
As more complicated microscope systems are engineered, the amount of effects taken into account rises steadily. In this context we experienced the need for a simulation approach, that...
