A Doppler Asymmetric Spatial Heterodyne (DASH) spectrometer includes an input aperture for receiving an input light; a collimating lens for collimating the input light into a collimated light; offset establishing means, including at least one grating, for i) receiving and splitting the collimated light into a first light wavefront in a first optical path and into a second light wavefront in a second optical path, ii) establishing an offset in a light wavefront path distance between the first and second optical path light wavefronts, and iii) diffracting and recombining the first and second optical path light wavefronts into an interference wavefront to form an interference image that includes a plurality of phase points of a heterodyned interferogram measured simultaneously over the path distance offset; and an output optics section comprising a detector for receiving the interference image and outputting an interference image pattern.

The present invention provides an imaging equipment. In an aperture fiation type imaging equipment, the problem is that: an image flicker is generated by a fluorescent lamp lighted in dependence on a commercial AC supply and a LED lighting, it is imposible to fix a shutter at the shutter speed at which the image flicker does not occur. Because each image in the imaging equipment for monitoring is very important information, it is necessary to still obtain the image in which a residual image or flicker is not present relative to to a moving imaging target even though the shutter speed is set at high speed. When a decision is made that the flicker is present, the timings of applying a discharging pulse and a charge readout pulse respectively are varied depending on a field in order to implement shutter speed control in a CCD sensor, so that the imaging equipment can be exposed to a portion of light falling into the same phase thereof within a luminescence period of the lighting during each field. After the start of the control, the phase point treatment is immediately performed, so that the timing of the exposure if the imaging equipment in the lighting period of lighting is set to ensure the part with maximum exposure amount to be exposed. Even though a light source emits light while being repeatedly lit and extinguished in a certain period, the exposure without flicker is performed.
