“…Single-photon detection also has applications in many fields where very high sensitivity detection of light is necessary. For example, in biophotonics applications the photon emission rate is often low and the relative working time with samples frequently necessarily short so that reliable and efficient single-photon detectors are essential [15]. Timeresolved photoluminescence of semiconductor structures will also require the examination of very low photo-generated carrier densities which necessitates highly efficient, low-noise detectors [16].…”

Photo counting imaging is a promising imaging method for very low-level-light condition and super high-speed imaging.An experimental setup with Geiger mode silicon avalanche photodiode single-photon counter was established in this study. This experimental setup achieved photon counting imaging through serial two-dimensional scanning mode of single APD. It extracts the extremely weak signal from the noise by scanning image, and then reconstructs the photon distribution image. The feasibility of the experiment platform was verified with many experiments. The resolution bar was scanned and imaged in different lighting condition. A Lena image was also scanned and imaged among several illumination conditions. The resolution ability and imaging quality are evaluated in different illumination surroundings.The imaging limited condition was concluded based on existing APD sensor. The experimental result indicates that the imaging based Geiger mode APD is an excellent candidate for very low level light imaging.

“…Note that, for background-limited applications, both the CCD and digitized approach have the same trend of square root improvement, but that the digitized approach eliminates any transfer noise contribution. The digital TDI approach is also compatible with photon-counting pixel architectures [4], [5].…”

A digital focal plane array (DFPA) architecture has been developed that incorporates per-pixel full-dynamic-range analog-to-digital conversion and orthogonal-transfer-based realtime digital signal processing capability. Several long-wave infrared-optimized pixel processing focal plane readout integrated circuit (ROIC) designs have been implemented, each accommodating a 256 × 256 30-μm-pitch detector array. Demonstrated in this paper is the application of this DFPA ROIC architecture to problems of background pedestal mitigation, wide-field imaging, image stabilization, edge detection, and velocimetry. The DFPA architecture is reviewed, and pixel performance metrics are discussed in the context of the application examples. The measured data reported here are for DFPA ROICs implemented in 90-nm CMOS technology and hybridized to Hg x Cd 1−x Te (MCT) detector arrays with cutoff wavelengths ranging from 7 to 14.5 μm and a specified operating temperature of 60 K-80 K.
