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.

eMagin's micro-OLED Product Line

New England Chapter for the Society for Information Display in cooperation with the NES/OSA, will be holding its annual members dinner at the Sheraton Hotel in Framingham, MA on March 8. Dr. Amal Ghosh from eMagin will be the guest speaker for the evening presenting a technical and market oriented talk on eMagin's micro-OLED product line.

Area companies are invited to participate in during the pre-meeting table top trade show. Interested companies should contact Jignesh Gandhi (This email address is being protected from spambots. You need JavaScript enabled to view it.) for information about the exhibit.

March 20, 2012 - Student/Industry Forum

Student/Industry Forum

Location: Boston University
Note that this meeting will be held on a Tuesday

The NES/OSA in association with the OSA Student Chapter at  Boston University, the IEEE Photonics Society and the Optical Society of America will be holding our annual Forum on Optics Jobs in New England. The optics industry is invited to join area students to talk about what graduates can look forward to when they have completed their formal education. The program will include speakers sharing their insights and experience making the transition from student to industry.

Forum Speakers will include:

The meeting will begin with networking including refreshments and a light meal, followed by a panel of up to four 10-15 min talks and a Q&A session, finishing with time for further discussions. Our industry panel will draw speakers from New England's diverse industrial base such as Aerospace, Metrology, Lighting and Bio-Medical.

We encourage our regular members to bring their stories, feel free to share any information about your companies or institutions, and we welcome postings for jobs or internships.

GaN-based Nanocolumn Emitters and related Technologies

Joint Meeting with Boston IEEE Photonics Society

GaN nanocolumns, one-dimensional columnar nanocrystals, possess low dislocation and high light extraction efficiency properties; thus, the nanocolumns have a great potentiality to improve substantially the luminous efficiency in the green-to-red emission region. Periodically arranged GaN nanocolumns, in each of which an InGaN/GaN multiple quantum well (MQW) was integrated, were fabricated by a Ti-mask selective area growth (SAG) technique by rf-MBE for GaN. Using the uniform arrays of InGaN-based nanocolumns, we demonstrated successful optically pumped stimulated emissions in the blue-to-green emission range and operation of green emission InGaN-based nanocolumn LEDs; then, a novel technology for controlling the In composition of InGaN quantum wells on the same wafer was developed, which paved the way for the monolithic integration of three-primary-color light-emitting diodes.

Clinical Confocal Imaging: Concept to Commercialization

Meeting Location: Rebecca's Cafe, Grove Street, Newton

Clinical confocal imaging (a.k.a. reflectance confocal imaging) is capable of clearly imaging living cells in the skin and other human epithelial tissues for the purpose of real-time pathologic diagnosis of skin cancer and other diseases in a physician’s office, with out the need for an invasive surgical biopsy. This presentation will follow the development of this medical technology from its initial concept, through development and clinical studies, and finally to its worldwide commercialization. The discussion will include the technological, clinical and business aspects of the development of a medical device.
