Abstract:
An optical device for corneal measuring includes a light source module, a first optical module, a second optical module including a reference mirror, a light splitter and an image analysis unit. The light of the light source module is transmitted to the first and second optical modules through the light splitter. The light is transmitted to a cornea through the light splitter and the first optical module and reflected by the cornea to form a first light, the light is transmitted to the reference mirror through the light splitter and reflected by the reference mirror to form a second light. The first and second lights are transmitted to the light splitter and the image analysis unit. The reference mirror moves along a first direction, and when the first light and the second light interfere with each other, a relative optical path length is obtained.

Abstract:
A method of operating a portable biochemical testing apparatus is 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:
A spectrometer is disclosed. The spectrometer includes a fiber input, a collimator lens, a rotating shaft, a grating, a focal lens and a focal plane which have arranged in order. A broadband incident light of the fiber input becomes a first parallel beam through the collimator lens and separated by the grating into multiple parallel beams of different wavelengths and then focused by the focal lens to emit an output beams to an imaging position on the focal plane. The spectrometer can rotate the collimator lens and fiber input to change the imaging position on the focal plane.

Abstract:
An optical apparatus includes a light source, an optical coupling module, a reference light reflection module, and a data processing module. The light source provides an incident light. The optical coupling module divides the incident light into a reference light and a detection light emitting to the reference light reflection module and the object respectively. The reference light reflection module reflects the reference light and rapidly change the optical path of the reference light. The optical coupling module receives a first reflected light generated by the reference light reflection module reflecting the reference light and a second reflected light generated by the object reflecting the detection light and it interferes the first reflected light and second reflected light to generate a light interference signal. The data processing module receives and analyzes the light interference signal to obtain an optical detection result related to the object.
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.
