Poster summary

While single photon imaging has become crucial in many areas, applications are still limited to the visible region of the spectrum where detector noise performance is favorable. We present a full-field, holographic imaging system capable of imaging at the single-photon level in the shortwave infrared, despite the camera having a noise floor ≈200 times higher. We believe our demonstration will extend the range of applications of low-light imaging to other challenging detection regimes benefiting biological, medical, and covert imaging.
