The conventional discrete Fourier transform can be extended to a discrete Extended Fourier transform (EFT). The EFT allows to work with discrete data in close analogy to the optical bench, where continuous data are processed. The EFT includes a capability to increase or decrease the resolution in Fourier space (thus the argument that CCD cameras with a higher number of pixels to increase the resolution in Fourier space is no longer valid). Fourier transforms may also be shifted with arbitrary increments, which is important in electron holography. Still, the analogy between the optical bench and discrete optics on a computer is limited by the Nyquist limit. In this abstract we discuss the capability with the EFT to change the initial sampling rate si of a recorded or simulated image to any other(final) sampling rate sf.

The effect of temperature variation on Fourier transform infrared (FT-IR) spectrometer response stability is investigated for wavenumbers from 10,000 to 100 cm−1 with the use of a temperature measurement and data acquisition system on the spectrometer optical bench. Spectrometer response instability is correlated with local temperature variation for two FT-IR spectrometer systems, with the use of various infrared source, beamsplitter, and detector combinations. The data obtained show that detector responsivity variation and beamsplitter misalignment associated with thermal instability of the spectrometer optical bench are responsible for the observed response instability. Response variation of up to 4% per °C temperature variation is observed. Variations of the laboratory environment and spectrometer purge gas supply temperatures are shown to affect spectrometer thermal stability directly.

As an important part of laser interferometry system, optical bench is one of the core technologies for the detection of spaceborne gravitational waves. As the first step of the space Taiji program, Taiji-1 provides the measurement accuracy of laser interferometry system better than 100 pm/Hz[Formula: see text](@10 mHz–1 Hz). Taiji-1 is required to be able to track the motion of test mass in inertial sensor. According to the requirements, four interfering optical paths were designed. By adopting an integrated satellite design and selecting the optical and mechanical materials with low linear expansion coefficient, the high stability of optical path was achieved. By using the DOE method, the alignment errors (position/attitude) of four optical paths were all reduced to below 50 [Formula: see text]m/100 [Formula: see text]rad. In the performance test, the accuracy of laser interferometry system was better than 100 pm/Hz[Formula: see text](@10 mHz–1 Hz), and the modulation signal of inertial sensor was successfully detected. The results show that all technical indexes of optical bench have met or exceeded the design requirements.
