A method for imaging objects through turbid media includes generating a repetitive pulsed light beam under control of a pulse shaper, propagating the light beam through turbid media, and receiving and imaging the light beam at a sensor. Propagation through turbid media causes scattering of the light, and the sensor captures scattered pulses to produce an image. The pulse shaper controls pulse width, frequency, repetition rate and chirp of the generated light pulses according to a feedback signal received from the sensor, to improve image quality. A system for imaging objects through turbid media includes a laser for generating a light beam; a pulse shaper for controlling said light beam, and a sensor, in communication with the pulse shaper, for capturing the image of said light beam through a turbid medium. Pulse width is less than 250 femtoseconds to reduce attenuation of the light beam through the turbid medium.
