1, INTRODUCTION

The system conducts Touch DNA search and collection by special spectrum.

The special spectrum imaging technique system is aiming at discriminating, locating and extracting micro-scale Touch DNA correctly which are invisible and hidden in complex and diverse objects.

2, FEATURES

1) Integrated visualization design meets the needs of single person operation.

2) No interference from ambient light, no need DNA reagents.

3) Non-touch method to search and locate skin cells, avoid to contaminate the Touch DNA.

4) Multi-directional and wide-range searching

5) Easy for correctly abstraction and will not damage DNA evidence chain.

3, APPLICATION

1) Wide-range searching the evidence in crime field, like various implements, window edges, walls, and rounghness solid objects like bricks, sticks, letter paper, clothing and washed physical evidences, can be correctly locating and extracting.

2) Reveal the Touch DNA by searching and zooming in on objects like wooden handles, metal handles, alluminum alloy doors/windows, clothings, brick surface and packaging bags.

3) Seach for evidence on micro-scale splashing or dripping blood on dark cotton clothing, fiber fabrics and black tiles.

4) Locating, discriminating and extracting biological evidences like saliva, semen stian and urine traces.

5) Reveal perspiration stains on objects like floor, tabletop, painted wooden door surface which with complicated background, and objects on switch box, silicone box and other plastic containing fluorescer.
