摘要:
A method for classifying a plurality of object image regions of an object to be detected using a scanning microscope includes labeling each of the image areas of the object with a different marker so that light of a respective characteristic emanates from each marker. The intensity of the light from each marker is detected using at least two channels so as to generate detection signals, each detection signal being a function of the intensity of the detected light. The object regions are classified using ratios of the detection signals.
摘要:
A fluorometer for sensing the fluorescence of a sample utilizes an optical energy source for exciting a sample to be tested and an optical energy detector for detecting the emitted energy from the excited sample. Drive electronics are used for positioning the sample with respect to the optical components allowing a plurality of sample regions to be tested. A processor is utilized to control the operation of the test in accordance with test instructions and for processing the emitted energy detected from the sample to determine test results. A ROM chip socket accepts a plurality of ROM chips, wherein each ROM chip stores test data sets for one or more test types to be performed. ROM chips can be swapped to allow the fluorometer to be configured and reconfigured to perform a plurality of different tests. A communications interface facilitates the sharing of test information between the fluorometer and external entities.

A method for measuring and analyzing bioluminescence, including the steps of receiving in real-time a luminescence measurement result group from a creature sample group, displaying and maintaining in real-time the luminescence measurement result group, receiving in real-time another luminescence measurement result group from the creature sample group, and displaying and maintaining in real-time the another luminescence measurement result group, instead of the luminescence measurement result group.
摘要:
A microscope capable of being shaped into a beam with complete hollow shape by removing the disorder of the wavefront to the erase light, particularly, and capable of improving the spatial resolution by inducing a super-resolution near the limit, is provided. In the microscope, wherein a first light to excite a molecule from a ground-state to first electron excited state or a second light to excite the molecule from the first electron excited state to the second electron excited state with higher energy level, for a sample 56 including the molecule with three electronic states including at least a ground-state, are spatial phase-modulated into the prescribed beam shape, and parts of these first light and the second light are overlapped and focused to detect luminescence from the sample 56, a wavefront compensation means 61 is provided in the optical path of the first light and/or in the optical path of the second light, and the wavefront aberration caused in the first light and/or in the second light, is removed by the wavefront compensation means 61.
摘要:
A printed circuit device used in conjunction with inductive power and data transmission applications is formed substantially of ferrite material, with an inductive coil conductor formed around the substrate to increase the electromagnetic properties of the coil for both power and data transmission functions, thereby eliminating the need for a discrete ferrite core wire-wound coil to be connected to the circuit device.
摘要:
A fluorescence measuring apparatus is arranged to measure, substantially at the same time, a plurality of samples in a sample chamber or a plurality of points of the same sample, with the use of an excitation light source. The fluorescence measuring apparatus has a rotary sample stand (2) at the excitation light irradiation position, a plurality of through-holes (2a) are formed in the circumference of the rotary sample stand (2), and a sample placing unit (3) is insertable in each of the through-holes (2a). By moving the sample stand (2) relatively to the excitation light irradiation position, fluorescence measurement can be made on a plurality of samples without sample replacement required in a sample chamber (1).
摘要:
A banknote inspection apparatus has a conveyance path, and midway of this conveyance path there are conveyance rollers for conveying a banknote, and a fluorescence sensor for detecting a fluorescent component included in the banknote. The fluorescence sensor has a housing and in this housing there are a light-emitting device for emitting light toward a banknote, and a light-detecting device for detecting fluorescence emitted from the surface of the banknote irradiated with ultraviolet light. A fluorescent member that generates fluorescence in response to the light emitted from the light-emitting device is placed in an inspection area of the conveyance path. In inspection of the banknote, the quantity of fluorescence from the fluorescent member is first detected, and the quantity of the light emitted from the light-emitting device is corrected based on the quantity of the fluorescence detected. Then the content of the fluorescent component in the banknote is detected in that state.
摘要:
Optical fiber sensors and fiberless optical sensors for measuring analytes, and in particular nitric oxide, are described utilizing metals, and more particularly, metal colloids. Proteins (or fragments thereof) with selective binding are immobilized on metal particles. The proteins may be dye-labeled for increased sensitivity.
摘要:
An apparatus and method for monitoring a large number of binding interactions and obtaining data related to the interactions. In accordance with the illustrative embodiment, the apparatus includes an IR sensor, a sliding separator, and IR-transmitting fibers that are optically coupled, at a first end thereof, to the sensor. The sliding separator adjusts the spacing between fibers as is required for interfacing the second end of the fibers with any of a variety of sample carriers. The second end of the fibers capture chemical entities form the sample carriers. The chemical entities at the end of the fibers are then contacted with a binding compound. If binding activity occurs, a thermal signal indicative thereof will be transmitted through the fiber to the sensor.
