Abstract:
An image-recognition assisting method includes the steps of using an examination instrument to generate an image having a split-image area formed thereon; setting a region-of-interest (ROI) around the split-image area of the generated image; performing a pixel luminance addition processing on the ROI, so that all pixels in the ROI have increased luminance contrast; and performing a contrast correction on the ROI having increased luminance contrast, so that the luminance contrast between the split-image area and the area surrounding the split-image area in the ROI is further increased. The image-recognition assisting method optimizes the image generated by the conventional ophthalmic examination instrument, such as a fundus camera, to increase the sharpness and the luminance contrast of the image output by the fundus camera, so that an examiner can easily recognize two offset rectangular image parts in the split-image area and align them with each other to focus the examination instrument.
Abstract:
A fundus examination device aiding in gaze fixation and image focusing includes a light projecting device for projecting an examination light to illuminate an examinee's fundus; an illuminating system for transmitting the examination light to the examinee's eye and receiving a fundus image; an imaging system for showing the fundus image; and a focusing and gaze-fixation device located in the illuminating system and including a focus mask formed in a focusing zone, on which the examinee's eye focuses. The focus mask includes a split image screen surrounded by a light-penetrable structure, and gaze fixation devices for forming gaze-fixation images at examinee's eye focusing positions within the focusing zone, such that the split image screen and the gaze-fixation images are located at different focal positions corresponding to the examinee's eye curvature. Therefore, when a split image focusing is completed, the gaze-fixation images are also located at clearly recognizable focal positions.

A large area optical diagnosis apparatus and the operating method thereof are disclosed. The large area optical diagnosis apparatus includes a light source, a light path structure, and a sensing module. The light source is used to at least emit a coherent light. The light path structure includes a plurality of optical units used for dividing the coherent light into a plurality of first incident lights and a plurality of second incident lights. The plurality of first incident lights are emitted toward an object to be diagnosed and the plurality of second incident lights are emitted toward a reference end. The object to be diagnosed and the reference end reflect the plurality of first incident lights and the plurality of second incident lights to be a plurality of reflected lights. The sensing module senses the plurality of reflected lights to generate a sensing result related to the object to be diagnosed.
Abstract:
A portable biochemical testing apparatus and operating method thereof are disclosed. The portable biochemical testing apparatus includes a light source module, a sample module, a photoconductive material layer, a touch module, and a control module. At least one sample is disposed in the sample module. The photoconductive material layer is disposed between the sample module and the light source module. The touch module generates a driving signal according to a touch action of the user to drive the light source module to emit a light. When the light is emitted to the photoconductive material layer, the photoconductive material layer will generate a photoelectric driving effect. The at least one sample is affected by the photoelectric driving effect and generates a change corresponding to the touch action.
Abstract:
An optical detecting apparatus and an operating method thereof are disclosed. The optical detecting apparatus includes a light path module, an actuating module, and a data processing module. The light path module is used to emit a light source to a substance and receive an optical signal generated by the substance reflecting the light source. The actuating module is used to actuate the substance to generate a vibration. The data processing module is used to record and analyze a detected result related to the material properties of the substance and adjust detecting parameters of the light path module and the actuating module respectively.
Abstract:
An optical coherence tomography apparatus includes a light source, a light coupling module, and an optical path difference generating module. The light source emits a coherent light. The light coupling module divides the coherent light into a first incident light and a second incident light. The first incident light is emitted to an item to be inspected and a first reflected light is generated. The second incident light is emitted to the optical path difference generating module, a second reflected light is generated according to the second incident light by the optical path difference generating module through changing the transparent/reflection properties of at least one optical devices of the optical path difference generating module, so that there is a optical path difference between the first reflected light and the second reflected light.
Abstract:
A continuous testing method for testing the concentration of a target object in a fluid is provided. The method comprises the following steps. A focused light is provided in the fluid to separate the target object from a non-target object in the fluid by changing the movement direction of the target object and the non-target object. The fluid having separated out the non-target object is enabled to react with a reagent. A signal is provided to pass through the fluid having reacted with the reagent. The signal passing through the fluid is received and an electronic signal is outputted corresponding to the input signal. The concentration of the target object is acquired according to the electronic signal.
