Abstract

Three-dimensional images of objects with very low reflectivity are obtained through a nonlinear upconversion gating with amplified femtosecond laser pulses. The current sensitivity of 10−10 of the incident pulse intensity can be improved by use of better nonlinear crystals and higher-intensity gating pulses. The intensity rejection ratio between two coherent pulses with a delay of a few millimeters between them is better than 2 orders of magnitude. The depth resolution is ∼15 μm. The transverse resolution of 300 μm is mainly limited by the two-dimensional detector that was used.
