An Amplified MOS Image Sensor with Horizontal 3 Line Outputs.

Lensless Photography with only an image sensor

Photography usually requires optics in conjunction with a recording device (an image sensor). Eliminating the optics could lead to new form factors for cameras. Here, we report a simple demonstration of imaging using a bare CMOS sensor that utilizes computation. The technique relies on the space variant point-spread functions resulting from the interaction of a point source in the field of view...

Scalable line-based wavelet image coding in wireless sensor networks

Single sensor that outputs narrowband multispectral images.

We report the work of developing a hand-held (or miniaturized), low-cost, stand-alone, real-time-operation, narrow bandwidth multispectral imaging device for the detection of early stage pressure ulcers.

ingle sensor that outputs arrowband multispectral mages

arly stage pressure ulcers and other subcutaneous lesions are early invisible in clinical settings, particularly so for dark igmented skin. An earlier study indicated multispectral imges can enhance the contrast between damaged and normal kin. Although multispectral imaging has matured into a techology with applications in many fields, clinical practitioners n the fields of health care and reha...

Photon Counting Imaging with an Electron-Bombarded Pixel Image Sensor

Electron-bombarded pixel image sensors, where a single photoelectron is accelerated directly into a CCD or CMOS sensor, allow wide-field imaging at extremely low light levels as they are sensitive enough to detect single photons. This technology allows the detection of up to hundreds or thousands of photon events per frame, depending on the sensor size, and photon event centroiding can be emplo...
