The imaging performance of a high speed camera utilizing novel "on-chip electron multiplication gain CCD (EMCCD)" technology is presented. The EMCCD technology has become a popular choice for low-light, high-speed scientific imaging and spectroscopy

Traditionally, scientific camera systems were partitioned with a `camera head' containing the CCD and its support circuitry and a camera controller, which provided analog to digital conversion, timing, control, computer interfacing, and power. A new,

CCDs have been used in spectroscopy for a number of years and for all the obvious reasons. Unfortunately most scientific CCDs are square arrays and are not ideally formatted for spectroscopic applications. This paper discuses the design and fabricati

A novel combination of techniques with a proprietary masked CCD allows economical commercial realization of a fast framing camera which can acquire images at 4,000 frames per second while maintaining the low readout noise of a slow scan scientific gr

Most of the personal computers in the US are in small businesses and are not networked. Small businesses have special needs which haven't been fully addressed by traditional LAN systems. This paper will explore these requirements and show how wireles

An equation for the random noise of self-scanned silicon photodiode arrays is developed which includes significant terms not previously considered. It is shown that, including these terms, the new 2.5-mm-high self-scanned arrays are only slightly noi

A method for fabrication of an inexpensive platinum electrode is presented. The process is based on the thermal deposition of a Pt film upon a glass substrate yielding a chemically inert electrode; the electrode is amenable to Pt blacking. The measur

A digital radiography system using self scanning linear diode arrays is being developed for improved diagnosis at reduced radiation dose. Our technique is based on the use of solid state sensors with 1024 diodes per inch and with very high dynamic ra

The ac and dc induced nonlinearities of platinum electrodes in KCI solution were investigated and the effects of the rectification were significant only in the presence of externally applied dc. The experimental dependence of the overpotential as a f
