Patent ID: 7365849

Claim:
A portable, scanning and analyzing apparatus, used to scan a test paper and the test paper comprises a test sample thereon, the scanning and analyzing apparatus comprising: a scanner device, for scanning the test paper and outputting a test signal corresponding to the test sample, wherein the scanner device comprises an integrated modular scanning probe comprising at least a light emitting diode (LED) array light source and at least a photodiode detector array assembled together in the integrated modular scanning probe, wherein the LED array light source emits a light to the test paper and the test paper reflects the light to the photodiode detector array, wherein the light from the LED array light source is incident to a surface of the test paper by an incident angle of 45 degrees from a normal direction of the surface of the test pate and the test paper reflects the incident light by deflecting 90 degrees from the incident angle; a computing unit, coupled to the scanner device to receive and analyze the test signal, wherein the computing unit receives an incoming command and accordingly outputs a control signal; a controller, coupled to the computing unit, wherein the controller outputs a driver signal in accordance with the control signal received; and a driver device, coupled with the controller device and the scanner device, wherein the driver device receives the control signal and accordingly drives the scanner device to scan the test paper.
