Abstract:
An apparatus comprising:a. a biochip configured for supporting an array of samples;b. a sensor configured for detecting emitted light from the array of sample;c. a single source board spectrum light source optically coupled to the sensor configured to illuminate the array of samples on the biochip with an excitation light having a first excitation wavelength and a second excitation wavelength;d. a matched filter optically coupled between the array of samples and the single source board spectrum light source for selecting between the first excitation wavelength and the second excitation wavelength to pass therethrough and strike the array of samples; ande. a matched filter optically coupled between the sample and the sensor for selecting between emitted light having a first emission wavelength and a second emission wavelength to pass therethrough and strike the sensor, the a first emission wavelength and a second emission wavelength resulting from the first excitation wavelength and the second excitation wavelength striking the array of samples, respectively.
