Time-multiplexed optical waveform generation for high-resolution imaging
Autor: Kevin W. Holman, Sumanth Kaushik, David G. Kocher
Publikováno v: 2008 Conference on Lasers and Electro-Optics.
We have developed a time-multiplexed technique for controlling the amplitude and phase of the individual frequency components of a mode-locked laser to generate a precisely linear chirped waveform. We have demonstrated a 20-GHz, 1-mus chirp.

MIT/LL development of broadband linear frequency chirp for high resolution ladar
Autor: David G. Kocher, Kevin W. Holman, Sumanth Kaushik
Publikováno v: SPIE Proceedings.
The development of a high-resolution laser radar (ladar) exhibiting sub-mm resolution would have a great impact on standoff identification applications. It would provide biometric identification capabilities such as three-dimensional facial recogniti

Publikováno v: Applied Optics. 41:7671
We have developed a threedimensional imaging laser radar featuring 3-cm range resolution and single-photon sensitivity. This prototype direct-detection laser radar employs compact, all-solid-state technology for the laser and detector array. The sour

Satellite vibration measurements with an autodyne CO_2 laser radar
Autor: Shalom Fisher, Kenneth I. Schultz, J. A. Daley, David G. Kocher, Joseph R. Theriault, J. Spinks
Publikováno v: Applied Optics. 33:2349
Vibration signatures of the Low Power Atmospheric Compensation Experiment satellite were obtained with a ground-based CO(2) laser radar. The laser radar operated in a cw mode and used autodyne receivers to extract relative target velocity information

Point Image Focus Sensing Using An Automated Foucault Test
Autor: David G. Kocher
Publikováno v: Wavefront Sensing.
An electromechanical focus sensing technique for isolated point or small spot images is described. The technique is a mechanization of the Foucault knife-edge test, and it works with either laser or white light. The focus sensor provides an output vo
