Abstract

A high-resolution computer indicating device comprises a light source, a sensor and a wavelength modulation medium. The sensor is used for sensing reflection signals reflected by a surface irradiated by the light source; and the wavelength modulation medium is at least configured before a sensing reflection device and between incident light of the light source and the surface, wherein the refractive index of the medium is larger than 1, so that the wavelength of the light source is reduced, and resolution ratio is improved.

Description

【Technical field】 [0001] The present invention relates to a computer pointing device, in particular to a high-resolution computer pointing device. 【Background technique】 [0002] With the advancement of technology, electronic products are constantly developing towards thinner and smaller features, such as digital cameras, computer cameras, mobile phones with image capture devices, etc. Therefore, the optical components or devices of these electronic devices must also be miniaturized In line with technological development trends. The computer usually uses a cursor pointing device to click or issue instructions, and the above-mentioned cursor pointing device usually includes a mouse. The usual components of a mouse include a housing containing components such as circuit boards (see figure 1 ), the housing also includes a light source 100, a sensor 106, lenses 102, 104, etc., and the light source emits light with a wavelength to the surface 108 of the object, such as a tablet...
