Off-axis Fresnel digital holography at terahertz frequencies

Conference Paper

An Off-axis Fresnel interferometric imager was constructed to acquire holograms using a highly coherent, narrowband, continuous wave source tunable over 0.3-1.0 THz. Fresnel and angular spectrum reconstruction methods of amplitude and phase holograms are presented and compared. While transverse resolution was on the order of the wavelength, unprecedented depth resolution of nearly λ/300 (2 μm) is reported.
