For busy archaeologists struggling with processing of large find assemblages, the Laser Aided Profiler (LAP) device employs the latest technology for high-quality, rapid, digital documentation of ceramic fragments. The LAP alleviates the tedious drawing task, allowing you to fully concentrate on your research. Resulting data are stored in an easily accessible database, so you can feed them into data-analytic pipelines and take your research to the next level.
Drawing of a ceramic fragment created using the LAP.
You can use the LAP in the lab as well as in the field. The device is built on industrial-grade components that can withstand dusty environments and temperatures of over 40 degrees Celsius. It is easily portable, with assembly and disassembly taking just a few minutes.
For extreme robustness in long-term usage, there are no moving parts and the data acquisition is purely optical. Thanks to advanced synchronization technology, the image capturing is reliable even in places with strong ambient sunlight. Still, the lasers are kept eye-safe for the operator.
The LAP comes packed in a handy suitcase. Measuring 46 x 34 x 15 cm (18 x 13 x 6 inches) and weighing under 7 kg (15 lb.), its size and weight fall within standard airplane cabin baggage limits, so you can keep the LAP safely with you while travelling.
Two lasers (a, e) project laser lines onto the specimen from both sides. The cameras (d, f) capture the projected lines to produce a 3D section of the fragment. The high-resolution color camera (b) together with LED illumination (c) complete the final drawing with a 2D photograph.
The bundled software application streamlines the drawing process for you to work at maximum efficiency while achieving high-quality outputs. Depending on the sample complexity, a skilled operator can produce up to 400 drawings per day. The digital data, metadata and complete drawings are saved into an open-source database for later querying or processing.
All drawings are in scale and immediately ready to be published. The acquired data are readily available for subsequent processing, e.g. shape-matching or morphometric analysis.

The LAP is currently used at the following institutions:
The LAP idea was conceived over a cup of tea between two friends with different professional backgrounds. Peter is an archaeologist specializing in computational modelling of past human activities relying on large digital datasets. Vladimír is an engineer skilled in optical measurement and inspection systems for manufacturing industries. Together we seek to bring high tech into archaeology.
The price of one LAP unit including the control software is € 4950 (shipping cost, duty or tax not included). We ship worldwide.
The lead time is 6 weeks from the purchase order. The standard warranty is 24 months. We also provide a money-back guarantee if you return the device within 30 days.
