A method for imaging objects (111) through turbid media (110) includes generating (602) a repetitive pulsed light beam (104) control of a pulse shaper (106), propagating (604) the light beam (104) through turbid-media (110), and receiving and imaging the light beam (107) at a sensor (114). Propagation through turbid media (110) causes scattering of the light, and the sensor (114) captures scattered pulses to produce an image. The pulse shaper (106) controls pulse width (204), wavelength (202), repetition rate (206) and chirp (208) of the generated light pulses (104) according to a feedback signal (116) received from the sensor (114), to improve image quality. A system (100) for imaging objects (111) through turbid media (111) includes a laser (102) for generating a light beam,- a pulse shaper (106) for controlling said light beam (104, 105), and a sensor (114), in communication with the pulse shaper (106), for capturing the image of said light beam (104, 105, 107) through a turbid medium (110). Pulse width is less than 250 femtoseconds to reduce attenuation of the light beam through the turbid medium. |
