Abstract: An optical particle detection system includes a light source, a lens group, an absorber, a microscope group, a filter, an image sensor, and a host. Laser is emitted from the light source, the lens group is configured to reflect and expand the laser light. The absorber absorbs a plurality of particles and presents the particles to an optical path of the laser light expanded by the lens group. The microscope group amplifies an image of the particles. The filter filters the laser light from the microscope group. The image sensor converts the laser light filtered by the filter into an electrical signal and the host analyzes the electrical signal and determines quality and components of at least one target particle in the particles.

Abstract: A grating measuring module includes a light source, a collimating device, a first grating, a second grating, and an image sensing chip. The first grating is arranged on an optical path of the collimating device and the second grating is arranged on an optical path of the first grating. Each of the two gratings comprises a first pattern and a plurality of second patterns locating at the both sides of the first pattern. The first and second gratings can each be attached to an object which may be displaced in relation to another object, so allowing light of a certain pattern to pass depending on the magnitude of the displacement. The image sensing chip arranged on an optical path from the second grating receives light emitted from the light source and forms an image from which a displacement can be calculated and displayed.

Abstract: A system for precise measurement of current takes current from a current input terminal, the system includes a controlling unit, a voltage generating unit, a voltage amplifying unit, and a processing unit. After sampling the current, the controlling unit outputs a control signal to the voltage generating unit. The voltage generating unit converts the current into different voltage signals. The voltage amplifying unit amplifies the voltage signal, and outputs the amplified signal to the processing unit. The processing unit converts the amplified voltage signal to obtain a corresponding value of current. The system accurately measures currents of different magnitudes, and improves the accuracy of current detection.
