    Abstract: Methods and apparatus (10, 20, 25, 60, 70) for detecting variations in electromagnetic fields, in particular, terahertz (THz) electromagnetic fields, are provided. The methods and apparatus employ polarization detection devices (120) and controllers (224) to maintain or vary the polarization of modulated signals (212, 262) as desired. The methods and apparatus are provided to characterize electromagnetic fields by directing the electromagnetic field (204, 254) and a probe beam (206, 252) upon an electro-crystal (202, 256) and detecting the modulation of the resulting probe beam (212, 262). Detection of the modulation of the probe beam (212, 262) is practiced by detecting and comparing the polarization components (216, 218, 266, 268) of the modulated probe beam (212, 262). Aspects of the invention may be used to analyze or detect explosives, explosive related compounds, and pharmaceuticals, among other substances. A compact apparatus (10), modular optical devices (20, 25, 60, 70) for use with the apparatus, sample holders (400, 402, 500), and radiation source mounts (600, 650, 700) are also disclosed.

    Abstract: The surface of a doped semiconductor wafer (12) is heated locally by means (14) of a pump beam whose intensity is modulated at a first frequency (18). The heated area (12a) is sampled by a probe beam (42) whose intensity is modulated at a second frequency (46). After the probe beam (42) has been modulated (reflected or transmitted) at the first frequency by the wafer (12), the modulated probe beam (50) is detected at a frequency equal to the difference between the harmonics of the first and second frequencies to determine dose of the dopants in the wafer (12). Such or similar type of instrument for measuring dose may be combined with an ellipsometer (100), reflectometer or polarimeter for measuring dose as well as thickness(es) and/or indices of refraction in a combined instrument for measuring the same sample (12).
