Abstract: A device for irradiating ocular tissue, including a source of electromagnetic radiation; a beacon scattering the electromagnetic radiation transmitted through an opacity in ocular tissue so as to form scattered electromagnetic radiation; a modulator transmitting output electromagnetic radiation having a field determined from a recording of the scattered electromagnetic radiation transmitted through the opacity, so that the output electromagnetic radiation is transmitted through the opacity to the beacon. The device can be used to treat amblyopia or correct optical aberrations in corneal or lens tissue.

Abstract: Disclosed herein are systems and methods of phase-sensitive compressed ultrafast photography (pCUP). In some embodiments, a pCUP system comprises: a dark-field imaging system, and a compressed ultrafast photography (CUP system). The dark-field imaging system may comprise a laser source configured to illuminate the subject with a laser pulse; and a beam block configured to pass laser light scattered by the subject as a first series of phase images and block laser light not scattered by the subject. The CUP system may comprise: a spatial encoding module configured to receive the first series of phase images and to produce a second series of spatially encoded phase images; and a streak camera configured to receive the second series of spatially encoded phase images, to deflect each spatially encoded phase image by a temporal deflection distance, and to integrate the deflected phase images into a single raw CUP image.

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.
