Extreme Linear Dynamic Range Detection Using the Charge Injection Device
Charge transfer device optical array detectors are typically classified in three broad categories: charge coupled devices (CCDs) utilizing inter-pixel charge transfer for readout, charge injection devices (CIDs) utilizing intra-pixel charge transfer for readout, and CMOS devices. The latter devices are named for the standard semiconductor processes used in their manufacture rather than the charge transfer mechanism employed for readout. While CCDs are the preferred detectors for photon-starved scientific applications such as astronomy, and CMOS devices are the preferred detectors for high-volume commercial applications such as mobile phone cameras, the CID is the preferred detector for high dynamic range scientific applications such as inductively coupled plasma optical emission spectroscopy (ICP-OES) and particle beam profiling. Since CID pixels are randomly addressable and the photon-generated charge within the pixel can be quantified non-destructively using intra-pixel charge transfer, the integration time may be varied from pixel to pixel based upon the experimentally observed photon flux. Using this exclusive random access integration feature, unprecedented linear dynamic range exceeding 7 orders of magnitude has been demonstrated on full-frame images with a single exposure – several orders of magnitude beyond the capabilities of CCD and most CMOS detectors. The unique CID architecture is described, high-level CID camera capabilities are discussed, and several illustrative imaging applications are presented.
Michael Pilon, General Manager Thermo Fisher Scientific
Dr. Pilon has been the General Manager of Thermo Fisher Scientific’s CIDTEC Cameras & Imagers product line in Liverpool, NY since 2003. He received his PhD in Analytical Chemistry from the University of Arizona (Tucson, AZ) in 1991 where he was the first to utilize CID detection with an echelle spectrometer for ICP-OES. Upon graduation, Dr. Pilon accepted a position at Thermo Electron (Thermo Fisher Scientific’s predecessor) where his team commercialized this ICP-OES instrumentation. More than 7500 of the instruments have been sold, and they are employed in a wide variety of applications including environmental analysis, metals analysis, quality control, petrochemical analysis, geological analysis, etc. The CIDTEC Cameras & Imagers business manufactures CID cameras for this ICP-OES instrumentation as well as other unique solid-state cameras for a variety of OEM customers in the medical equipment, analytical instrumentation, nuclear power, and machine vision industries.

General Information on NES/OSA Meetings
Cancellations and No-shows:
If the meeting must be canceled for any reason, we will try to call you at the phone number you leave with your reservation. Official notice of cancellation will be on our answering machine.
We have to pay for the dinners reserved as of the Tuesday before the meeting, so no-shows eat into our cash reserve. If you will not be able to attend, please let us know as early as possible. Otherwise, no-shows will be billed.
NOTE: The extra $5.00 of the non-member dinner fee can be used toward membership dues if the nonmember joins and pays dues for the current year at the meeting.
