近年来，探测器技术和电子计时能力的进步为利用强度干涉测量法实现天文学超高分辨率带来了新的机会。我们一直在研究这项技术，并在这里描述我们所看到的潜力。目前存在两个单独的机会：使用单光子雪崩二极管（SPAD）探测器与现有的研究级望远镜和光电倍增管与光桶望远镜相结合。今后，天基强度干涉测量法也有潜力。虽然强度干涉测量法不太可能取代基于振幅的干涉测量法，但它在便携性、使用大基线、窄带成像和蓝色成像方面确实具有某些优势。由于这些原因，我们看到了一种新的可能性，特别是在恒星天体物理学中。
Advances in detector technology and electronic timing capabilities in recent years have resulted in a new opportunity for ultra-high resolution in astronomy using intensity interferometry. We have been working with this technology and describe here the potential as we see it. Two separate opportunities exist at present: the use of Single Photon Avalanche Diode (SPAD) detectors with existing research-grade telescopes and photomultipliers coupled with light bucket telescopes. In the future, there may also be potential for space-based intensity interferometry. While intensity interferometry is not likely to replace amplitude-based interferometry, it does have certain advantages in terms of portability, use of large baselines, narrow-band imaging, and imaging in the blue. We see a new possibility for its use particularly in stellar astrophysics for these reasons.
