Abstract
A test apparatus and a control method thereof are provided. The test apparatus is configured to test a sample in a reactor. The test apparatus includes at least one light emitter configured to emit light to chambers of the reactor, a light receiver configured to receive light passed through the chambers while scanning the chambers, and a processor configured to determine a position or an area of a chamber among the chambers, based on light receiving positions of the light receiver, and respective intensities of the received light. The processor is further configured to measure an optical density of light passed through the determined position or the determined area of the chamber.
Core Innovation
The invention relates to a test apparatus configured to test a sample in a reactor by using light transmission through multiple chambers in the reactor. At least one light emitter emits light to chambers, where each chamber includes a portion of the sample, and a light receiver receives light passed through the chambers while moving in a direction from a side of the reactor to another side of the reactor.
The processor generates a map comprising coordinates respectively of the chambers based on light receiving positions and intensities received at those positions. The coordinates comprise respectively pixel numbers of light receiving elements and the light receiving positions, which are along the direction from the side of the reactor to the other side of the reactor.
The processor determines a position or an area of a chamber, or a coordinate of a chamber, among the chambers based on the light receiving positions and intensities. After the chamber position, area, or coordinate is determined, the processor measures optical density of light passed through the determined position or determined area of the chamber.
Claims Coverage
The partial content includes two independent claims. Across the independent claims, the main inventive structure centers on moving light reception along the reactor direction, generating a coordinate map from pixel numbers and received intensity information, determining a chamber position/area or coordinate, and measuring optical density of transmitted light.
Generating a coordinate map from moving light receiving positions and intensities
The processor generates a map comprising coordinates respectively of the chambers based on light receiving positions at which the light receiver receives the light passed through the chambers, the light receiving positions being along the direction from the side of the reactor to the other side of the reactor, and based on intensities of the light received respectively at the light receiving positions, the coordinates comprising respectively pixel numbers of light receiving elements and the light receiving positions.
Determining a chamber position or area and measuring optical density
The processor determines a position or an area of a chamber among the chambers based on the light receiving positions and the intensities, and measures an optical density of light passed through the determined position or the determined area of the chamber.
Selecting a chamber coordinate from the largest received intensity
The processor determines a coordinate of a chamber among the chambers, the coordinate comprising a pixel number of one of the light receiving elements and a light receiving position of the light receiver, at which the one of the light receiving elements receives a largest intensity of the light passed through the chambers, the light receiving position being along the direction from the side of the reactor to the other side of the reactor.
The independent claims share a common inventive concept of identifying chamber location using a map based on moving light receiving positions and received intensity information tied to pixel numbers, and then using the determined chamber location to perform optical-density measurement or to determine a chamber coordinate based on a largest received intensity.
