Optical-mechanical assembly having optical track regulating mechanism

Abstract

The related optical assembly with optical-path regulation mechanism comprises: an optical sensor module, an optical assembly body to guide external light into the sensor, and a regulation mechanism with two elements to fix the module and body and regulate the relative distance or angle between the sensor and external light path, wherein the unit displacement of the regulation mechanism is equal to the difference of displacements of two elements. This invention is benefit to obtain optimal image.

Description

technical field [0001] The invention relates to an optical module, in particular to an optical module capable of adjusting the relative distance or angle between a light sensor and an optical path of external light. Background technique [0002] At present, most of the adjustment mechanism design technologies related to the optical path of the light sensor are concentrated and developed toward the trend of multi-directional adjustment. For example, in the technical field of optical path adjustment of CCD optical-mechanical components, there are at least two or more known technologies that can achieve the above-mentioned design goals. [0003] Taking the first known technology (Taiwan Patent Publication No.: 407826) as an example, the optical path adjustment mechanism disclosed therein can perform "up and down" (that is, along the z-axis direction), "left and right" (that is, along the y-axis direction) , "vertical rotation" (that is, rotate along the yz plane), "horizontal ...

AI Technical Summary

Problems solved by technology

[0005] The shortcoming of the second kind of known technology is that because the screw locked into the screw hole adopts a single-pitch screw, the resolution of the adjustment will be limited by the pitch.

However, these adjustment distances are obviously excessive adjustments and are not suitable for the current trend that the sensing point (pixel) distance of the CCD light sensor is gradually shrinking.

On the other hand, if you want to change the use of screws with a smaller pitch distance, you will also face the problem that the screws of this special specification are not easy to obtain, or the cost of obtaining them is too high
