Single-parameter estimation construction algorithm for Gm-APD ladar imaging through fog
, 2021When imaging through fog using Geiger mode avalanche photon diode (Gm-APD) ladar, strong backscattering photons make it difficult to effectively extract an accurate target signal via the traditional peak-select algorithm.

Large-area APDs and monolithic APD arrays
IEEE Transactions on Nuclear Science, 2001In this paper, development of large-area planar avalanche photodiodes (APDs) and monolithic APD arrays for X-ray and scintillation detection is discussed. Single APDs with areas as large as 10 cm/sup 2/ have been fabricated and tested with a CsI(Tl) scintillator (3.8 cm diameter, 2.5 cm height). The resolution of the 662 keV photopeak has been measured

My goal today is to make an argument that the APDS: is at a crossroads because of unprecedented changes; is in a great position to succeed; seeing the need for change we should nevertheless act consistent with our longstated principles/goals as we negotiate this new path we need to be resolute, bold and brave; the path I hope to convince you of, and ...

Planar processed APDs and APD arrays for scintillation detection
1999 IEEE Nuclear Science Symposium. Conference Record. 1999 Nuclear Science Symposium and Medical Imaging Conference (Cat. No.99CH37019), 2003In this paper, performance characteristics of new, planar processed silicon avalanche photodiodes (APD) and arrays are discussed for scintillation spectroscopy as well as direct X-ray detection. We have successfully fabricated large area APDs with sizes ranging from 1 cm/sup 2/ to 13 cm/sup 2/ using a novel planar process.

APD arrays and large-area APDs via a new planar process
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2000Abstract A fabrication process has been developed which allows the beveled-edge-type of avalanche photodiode (APD) to be made without the need for the artful bevel formation steps. This new process, applicable to both APD arrays and to discrete detectors, greatly simplifies manufacture and should lead to significant cost reduction for such ...
