“…They measure the power of electromagnetic radiation indirectly via the temperature-dependent electrical resistance of the detector material, typically amorphous silicon, vanadium oxide, or silicon nitride. Microbolometers designed for infrared applications represent an established technology field, with typical resolutions of 640 × 480 pixels, even though arrays of up to 1280 × 960 pixels can be found [80]. For many practical applications, the scene imaged by the thermal detector is at room temperature, where the noise content of the image is dominated by the thermal radiation noise.…”

Imaging with THz radiation has proved an important tool for both fundamental science and industrial use. Here we review a class of THz imaging implementations, named coherent lensless imaging, that reconstruct the coherent response of arbitrary samples with a minimized experimental setup based only on a coherent source and a camera. After discussing the appropriate sources and detectors to perform them, we detail the fundamental principles and implementations of THz digital holography and phase retrieval. These techniques owe a lot to imaging with different wavelengths, yet innovative concepts are also being developed in the THz range and are ready to be applied in other spectral ranges. This makes our review useful for both the THz and imaging communities, and we hope it will foster their interaction.

“…The specifications are summarized in Table 1. [2][3][4][5][6] The optics are very compact, but still provide enough room to insert a shutter for calibration purposes. Achieving good optical performance while allowing enough space for the shutter was a challenge for the optical design, as was reducing the effective thickness of the shutter.…”
