Abstract: Hyper-Heisenberg scaling quantum imaging techniques that pass an idler photon of each entangled photon pair three times through an idler objective pair and pass a signal photon of each entangled photon pair at least once through a signal objective pair and use measurements of coincidence detection to yield a coincidence image with spatial resolution of about four times that of classical imaging.

Abstract: A photoacoustic imaging system is disclosed that includes an ergodic relay coupled optically to a light source configured to produce a light pulse and further coupled acoustically to a transducer. The ergodic relay is further configured to direct at least two PA signals to the transducer. Each of the at least two PA signals are produced at different positions within the field of view of the object to be imaged in response to illumination by a single light pulse. The transducer detects each of the at least two PA signals after each of at least two delays that correspond to the position at which each PA signal was produced.

Abstract: Apparatus and methods for measuring infrared absorption of a sample that includes delivering a pulse of infrared radiation to a region of the sample, delivering pulses of radiation of a shorter wavelength than infrared radiation to a sub-region within the region, and using one or more properties of the induced photoacoustic signals to create a signal indicative of infrared absorption of the sub-region of the sample.
