A high-speed magnetic tweezer beyond 10,000 frames per second.

The magnetic tweezer is a single-molecule instrument that can apply a constant force to a biomolecule over a range of extensions, and is therefore an ideal tool to study biomolecules and their interactions. However, the video-based tracking inherent to most magnetic single-molecule instruments has traditionally limited the instrumental resolution to a few nanometers, above the length scale of s...

Imaging with an ultra-high-speed video camera working at 20 mega-frames per second

An image sensor with 300,000 pixels capable of operating at 20 mega-frames per second (Mfps) is developed. The pixels on odd-numbered and even-numbered columns can be switched on and off independently. Therefore, the max frame rate is 40 Mfps when only half of the sensor is activated. The sensor is a backside-illuminated one for high sensitivity to support ultra-high-speed imaging. The structur...

High frame rate photoacoustic imaging at 7000 frames per second using clinical ultrasound system.

Photoacoustic tomography, a hybrid imaging modality combining optical and ultrasound imaging, is gaining attention in the field of medical imaging. Typically, a Q-switched Nd:YAG laser is used to excite the tissue and generate photoacoustic signals. But, such photoacoustic imaging systems are difficult to translate into clinical applications owing to their high cost, bulky size often requiring ...

Million frames per second infrared imaging system

An infrared imaging system has been developed for measuring the temperature increase during the dynamic deformation of materials. The system consists of an 838 HgCdTe focal plane array, each with its own preamplifier. Outputs from the 64 detector/preamplifiers are digitized using a row-parallel scheme. In this approach, all 64 signals are simultaneously acquired and held using a bank of track a...

Integrated High Resolution Focal-Plane Polarization Imager

The polarimetric vector is a more general descriptor of light than intensity information alone, and it contains physical information about the imaged objects in a scene that traditional intensity based sensors ignore. Polarimeters – devices that measure polarization – are used to extract physical features from an image such as specularities, occluding contours, and material properties. Scientis...
