Abstract:
The present application relates to a colorimeter measurement method and a colorimeter for implementing the method. The method includes the following steps: placing a measured sample on a sample platform; shooting a current image of the sample; determining an intersection angle θ between the sample and a moving direction of the sample platform; adjusting a position of a scanning light spot of a colorimeter according to the angle θ, so that the sample coincides with the moving direction of the sample platform; using the colorimeter to scan the measured sample. By implementing the colorimeter measurement method and the colorimeter of the present application, the sample can be placed optionally when it is measured. Specially, when a design value of a measured sample is approximately equal to a size of the measuring light spot, much time can be saved and manpower waste is avoided.

Abstract:
The present invention relates to a method and system for fibre positioning in wide-field astronomy. In one form the method and system of the present invention relate to anchoring fibre end points adjacent or against the field plate of a telescope. In one embodiment the positioning system for anchoring a fibre end point at a location on a telescope field plate collocated with a telescope focal plane, the positioning system comprising a piezoelectric positioning device for positioning the fibre end point, the positioning device comprising a chamber having an opening, the opening lying against the field plate in use defining a substantially enclosed volume inside the chamber, a pump for reducing pressure inside the enclosed volume; and a path connecting the pump and the enclosed volume so that, in use, the pump effects a reduction in pressure in the chamber thereby anchoring the fibre end point on the field plate.
Abstract:
The present invention provides a wide-filed spectral imaging system including a laser generator, a wavelength adjustment module, an objective lens, and a single-pixel imaging and a spectral separating module. The laser generator is configured to generate a laser excitation beam. The wavelength adjustment module is configured to disperse the laser excitation beam into a plurality of beams of different wavelengths. The objective lens is configured to focus the plurality of beams of different wavelengths on a sample to excite molecules under test in the sample and generate an emission light. The single-pixel imaging and spectral separating module is configured to generate a series of patterns and modulate the emission light with the series of patterns to generate a diffracted beam. The single-pixel imaging and spectral separating module further disperses the wavelength of the diffracted beam, collects light signals of the expanded diffracted beam, and performs a spectral image reconstruction.
Abstract:
A scanning confocal microscopy system and apparatus, especially useful for endoscopy with a flexible probe which is connected to the end of an optical fiber (9). The probe has a grating (12) and a lens (14) which delivers a beam of multi-spectral light having spectral components which extend in one dimension across a region of an object and which is moved to scan in another dimension. The reflected confocal spectrum is measured to provide an image of the region.
