Problems solved by technology

[0004] However, the traditional optical sensor testing machine 1 needs to be equipped with the above-mentioned high-pressure discharge lamp 10, light processing device 11, and placement seat 12. Lamp 10 is a halogen bulb, not only the wavelength value of each wavelength component in the light source will drift and become unstable, but also the bulb wears out quickly. Therefore, it is a fatal flaw to test that the wavelength of the light source is stable during testing, and frequent replacement of bulbs also causes relative cost increase

Embodiment Construction

[0031] The foregoing and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description with accompanying drawings and several preferred embodiments.

[0032] Such as Figure 3-4 As shown, the light sensor detection device 2 with a built-in light source provided by a preferred embodiment of the present invention includes a base 20 , an upper cover 21 and at least one light emitting diode 22 . The base 20 has a carrying portion 200 . In this embodiment, a square placement space 23 is formed on the carrying portion 200 for placing a photosensor 3 (such as a CMOS or CCD chip) to be tested. The placement space 23 is not limited to the above-mentioned shape, and can also be a groove or any other common limiting structure. Such as Figure 4 As shown, in this embodiment, the bearing part 200 is evenly provided with a plurality of metal guide pins 24 around the bottom wall forming the placement space 23, for el...

Abstract

The invention discloses a test apparatus for an optical sensor with a light source therein, comprising a base and a cover on the base. At least one LBD is arranged on the cover and is used as the light source between the light source and to-be-tested optical sensor in the cover for the test. No high pressure discharge lamp or optical processing device is required in the invention, reducing the time waste in changing light source. In addition, the invention also discloses a test equipment of the test apparatus for optical sensor with inner light source.

Description

technical field [0001] The invention relates to a light sensor detection device, in particular to a light sensor detection device with a built-in light source; the invention also relates to a test machine for the light sensor detection device with a built-in light source. Background technique [0002] No matter in mobile phones, security monitoring fields or industrial detection equipment, optical sensors such as electrically coupled devices (CCD or CMOS) have been widely used. Therefore, the demand for detection of optical sensors is increasing day by day. Since optical sensors are mostly composed of a plurality of unit cells in an array, whether the response of each unit cell to the same intensity beam is the same determines the spatial uniformity of the optical sensor; and Whether the response of each unit cell to light beams of different wavelengths is the same determines whether the light sensor can achieve white balance; as for the response speed of each unit cell to t...
