    Abstract: There is provided a monochromator capable of downsizing thereof. According to a monochromator, a light transmission hole through which beam of light which is given out from a light source is transmitted and multiple plate-like filter blocks each having central axis of rotation which is parallel with beam of light are provided on a filter base. Various optical filters are attached to the holes of filter blocks and the filter block serves as a light shielding block. The filter blocks attached to the rotary shafts of motors are reciprocally rotated between a forward position of the optical transmission hole serving as a position of transmission of light and a standby position spaced away from the optical transmission hole so that the filter blocks can be downsized, and even if there are many patterns of combination of optical filters, multiple optical filters can be easily combined with each other and even if the optical filters are used singly or used while combined with each other, which does not take time for changing the optical filter, thereby enhancing efficiency compared with the conventional monochromator.

    Abstract: A cam filter wheel apparatus is disclosed for tilting interference filters in order to achieve variation in the light wavelength transmitted by each filter. The wheel apparatus contains a number of filters each mounted so as to pivot and change its inclination with respect to an incident light beam as the filter wheel rotates each filter through the light path. The pivot motion is achieved by a cam follower associated with each filter which rides on a stationary cam track.

    Abstract: An imaging system and method are presents for use in reconstructing spectral data of an object. The imaging system comprises: an optical unit; a pixel array of a detector; and a data processor for receiving and processing image data indicative of light detected by the pixel array and generating reconstructed spectral data of the object being imaged. The optical unit is configured and operable for applying a predetermined coding to an input light field while creating an optical image thereof on a detection plane defined by the pixel array. Therefore, the image data is a function of the predetermined coding and a spectrum of the object to be determined.

    Abstract: A shutter assembly comprising a first planar member and a second planar member opposed from one another and forming a sleeve having a cavity therebetween, the sleeve having a pair of side rails adjacent the cavity along sides of the sleeve. A first shutter member having a first end is disposed in the cavity and slidingly disposed along one of the side rails, and a second shutter member having a second end is disposed in the cavity and slidingly disposed along the other side rail. The first end is opposed to the second end and is configured to be selectively advanced towards, and retracted from, the second end so as to define an aperture therebetween having a first shape when disposed in a first position, and wherein the aperture has a second larger shape when the first end is disposed in a second position. The first shutter member and the second shutter member maintain a thermal contact with the side rails and the planar members in all positions. The shutter assembly is well suited to be used at a cryogenic temperature and in a high vacuum environment.

    Abstract: An optical spectrum analyzer is implemented with a detector combined with a tunable filter mounted on a stage capable of 360-degree rotation at a constant velocity. Because of the constant rate of angular change, different portions of the input spectrum are detected at each increment of time as a function of filter position, which can be easily measured with an encoder for synchronization purposes. The unidirectional motion of the mirror permits operation at very high speeds with great mechanical reliability. The same improvements may be obtained using a diffraction grating or a prism, in which case the detector or an intervening mirror may be rotated instead of the grating or prism.
