    Abstract: A linear-motion stage that is angularly or radially symmetric or asymmetric, or monolithic may be used as the moving mechanism in a Fourier transform spectrometer. In embodiments, a linear-motion stage includes a base; a first multiple-arm linkage extending from the base to a first carriage attachment piece; and a second multiple-arm linkage extending from the first carriage attachment piece to the base. The first multiple-arm linkage constrains a motion of the first carriage attachment piece to motion in a first plane and the second multiple-arm linkage constrains the first carriage attachment piece to motion in a second plane, the first and second planes intersecting at a plane intersection line. The first and second multiple-arm linkages constrain the motion of the first carriage attachment piece along a carriage motion line.

    Abstract: A Micro-Electro-Mechanical System (MEMS) apparatus provides for self-calibration of mirror positioning of a moveable mirror of an interferometer. At least one mirror in the MEMS apparatus includes a non-planar surface. The moveable mirror is coupled to a MEMS actuator having a variable capacitance. The MEMS apparatus includes a capacitive sensing circuit for determining the capacitance of the MEMS actuator at multiple reference positions of the moveable mirror corresponding to a center burst and one or more secondary bursts of an interferogram produced by the interferometer based on the non-planar surface. A calibration module uses the actuator capacitances at the reference positions to compensate for any drift in the capacitive sensing circuit.

    Abstract: Feedback control of an object which moves back and forth in a straight line along a linear guide is performed through PID control. A parameter adjustment unit which determines the control parameters to be used for PID control performs feedback control and determines the optimal value of control parameters by means of an evaluation function based on the error between the measured value of the current velocity and the target velocity, for the control parameters of maximum reverse voltage and at least one from among proportional coefficient (CP), differential coefficient CD), integral coefficient CI), and frictional coefficient (CF).

    Abstract: An imaging transform spectrometer, and method of operation thereof, that is dynamically configurable “on demand” between an interferometric spectrometer function and a broadband spatial imaging function to allow a single instrument to capture both broadband spatial imagery and spectral data of a scene. In one example, the imaging transform spectrometer is configured such that the modulation used for interferometric imaging may be dynamically turned ON and OFF to select a desired mode of operation for the instrument.
