A 110 × 64 pixel CMOS image sensor integrated with pixelated spectral interference filters is used for image guided surgery. The sensor operates with short exposure times for capturing visible light using blue, green, and red pixelated interference filters, and long exposure time for capturing near-infrared fluorescence with a co-located, pixelated NIR filter. The sensor was used to successfully detect...
We have designed, fabricated, and tested a division-of-focal-plane polarimeter capable of simultaneously imaging both spectral and polarization information at 30 frames per second. The imaging sensor, composed of 1300 by 800 imaging elements, each containing three vertically stacked photodetectors, is covered by pixelated nanowire polarization filters at four different orientations offset by 45º....

A 220 by 128 current mode imaging sensor with polarization sensitivity is used to image intrinsic neural activity in vivo from the antenna lobe of a locust. The polarization sensitivity is achieved via post-CMOS fabrication deposition of pixelated aluminum nanowire polarization filters at four different orientations offset by 45 degrees. The measured change in polarization response from the neural...
In this paper, we present recent work on bioinspired polarization imaging sensors and their applications in biomedicine. In particular, we focus on three different aspects of these sensors. First, we describe the electro–optical challenges in realizing a bioinspired polarization imager, and in particular, we provide a detailed description of a recent low-power complementary metal–oxide–semiconductor...
Polarization is a fundamental property of light for which humans have no innate detector. Numerous sensors have been devised to capture this property of light. Of these types of sensors, division of focal plane polarimeters allow for both high resolution and real-time capture of the angle and degree of polarization. This paper details a formal system of measurements designed to categorize the optical...
For many psychiatric conditions it is speculated that, rather than being single disease entities, they are a set of several disorders sharing clinical features but having (partly) different underlying causes. The possibility of measuring genetic variation on a large scale has given researchers new hope of identifying these disease subtypes that may differ with respect to prognosis, course, and response...
