Abstract:
An optical alignment method is for a light-emitting module that includes a housing unit, a light-emitting unit disposed in the housing unit, and a lens unit. The optical alignment method includes: (a) through image-capturing techniques, finding a light-emitting point of the light-emitting unit and a predetermined reference point, and determining a total optical path length between the light-emitting point and an imaging plane; (b) finding a first center line that divides the total optical path length in half; (c) through image-capturing techniques, finding opposite first and second edges of the lens unit, and determining a lens length between the first and second edges; (d) finding a second center line that divides the lens length in half; and (e) assembling the lens unit to the housing unit so that the first and second center lines overlap. A light-emitting module and an assembly method therefor are also disclosed.
Abstract:
A method for rapidly identifying a point mutation in porcine insulin-like-growth factor 2 intron 7 uses published primers to amplify the target DNA fragments by polymerase chain reaction. The DNA fragments are cloned and sequenced for confirmation and method validation. The key positions of the sequence are modified to generate three primers for amplifying different DNA fragments with different genotypes by PCR to avoid additional restriction enzyme digestion. A long primer is used to specifically amplify the lean muscle mass-enhancing allele, a short primer is used to specifically amplify the lean muscle mass-suppressing allele, and the third primer is shared and anneals to the complementary strand. After PCR and electrophoresis, samples with only the 92 bp band are identified as the CC genotype, samples with only the 72 bp band are identified as the GG genotype, and samples with both 92 bp and 72 bp bands are identified as heterozygotes.
Abstract:
An optical alignment method is for an optical module including a housing unit, a light-sensing unit, and a lens unit. The method includes: (a) through image-capturing techniques, finding a light-sensing component of the light-sensing unit and a predetermined reference point, and determining an actual total optical path length between the light-sensing component and an object position; (b) subtracting a correction distance from the actual total optical path length to obtain a corrected total optical path length; (c) finding a first center line that divides the corrected total optical path length in half; (d) through image-capturing techniques, finding opposite first and second edges of the lens unit, and determining a lens length between the first and second edges; (e) finding a second center line that divides the lens length in half; and (f) assembling the lens unit to the housing unit such that the first and second center lines overlap.
