The patent No. is the disclosed another kind of biochemical test bar detector of ZL200420110976.6, and this patent proposes fixedly miter angle irradiation sample of light source, and fiber transmission device is used to receive the sample light signal.The light source method is installed in the described inclination of patent ZL200420114298.0 and patent ZL200420110976.6, not only causes installation, debug difficulties, and makes that the utilization factor of light source is low.
The objective of the invention is to overcome deficiency of the prior art, a kind of detecting device of biochemical test bar simple in structure is provided, this device has higher sensitivity and resolution, and corresponding debug process is easy more.
Goal of the invention of the present invention realizes by following technical solution:
The present invention includes support, it is characterized in that: described support is provided with in order to settle the locating platform of biochemical test bar, also be provided with the photodetector that is positioned at the locating platform top on the support, described photodetector comprises that light source, photoelectric probe and upper port have the optical fiber of incident branch and reflection branch, described optical fiber lower port is just towards the locating platform in order to the arrangement biochemical test bar, and described light source and photoelectric probe lay respectively at the incident branch of optical fiber and reflect on the upper port of branch.
The light that light source of the present invention sends shines through Optical Fiber Transmission on the biochemical test bar that is positioned at the optical fiber below, and the light of reflection is via Optical Fiber Transmission and finally shine the photoelectric probe that is positioned at the optical fiber top, and photoelectric probe realizes opto-electronic conversion.
The present invention is by having the photodetector that light source, photoelectric probe and upper port have incident branch and reflect the optical fiber of branch, can realize the quantitatively detection of electric signal such as biochemical test bar surface test line, markings or background has been avoided adjusting this complicated process of light-source angle; The optical fiber lower port has not only improved the utilization factor of luminous energy but also has improved signal collected signal to noise ratio (S/N ratio) just towards biochemical test bar during use; Have good detection sensitivity and resolution, and one-piece construction is simple, installs, debug easy to use.
