The present invention relates to a portable digital reader for urinalysis. The portable digital reader for reading an analysis target chip including a plurality of test areas, comprises: a main body including a light emitting section having light emitting elements for radiating light, an integral optical splitter for uniformly distributing the light from the light emitting section to each test area of the analysis target chip, a light receiving section for receiving light reflected from the each test area so as to convert the same to electric signals, and a measuring section for measuring concentration according to the electric signals obtained from the light receiving section; a main supporting body having the analysis target chip and assembled with the main body; and an auxiliary supporting body assembled between the analysis target chip and the main supporting body, including a groove for assembling the analysis target chip, and assembled with the main supporting body to be exchanged after use. Therefore, it is possible to prevent the reader from being contaminated with superfluous urine by forming a portion contacting a strip chip to be exchangeable and disposing a moisture absorption material to a portion for introducing the strip chip.

Portable digital reader for urinalysis

The present invention relates to a portable digital reader for reading an analysis target chip including a plurality of test areas. The reader comprises: a light emitting section having light emitting elements for radiating light; an integral optical splitter for uniformly distributing the light from the light emitting section to each test area of the analysis target chip; a light receiving section for receiving light reflected from each test area so as to convert the same into electric signals; and a measuring section for measuring concentration according to the electric signals obtained from the light receiving section. Therefore, it is possible to prevent the generation of errors in signal measurement due to optical distribution failure by assembling branch sections of the optical splitter under the control of the number of the branch sections according to the number of test items in a test strip.

The present invention relates to an OPCPA apparatus. The OPCPA of the present invention includes an optical pulse stretcher () for outputting chirped laser light using odd-order dispersion (third-order dispersion is mainly used). A pump laser () outputs pump laser light. An OPA unit () receives the pump laser light and the chirped laser light (signal), amplifies the signal using the pump laser light, and generates an idler. An optical signal separation unit () separates output light of the OPA unit into the signal, the idler, and remaining light (pump). An optical pulse compressor () compensates for pulse chirping caused by odd-order dispersion that is imparted by the optical pulse stretcher, thus temporally compressing the signal and the idler, which overlap each other.
