A system for managing requests for setting up computer test environments includes a setup request database storing the test environment setup requests and a request management module which provides a standardized user interface screen to submit the requests. It can solve problems raised by describing hardware using programming language, e. Even when each LED has a small light quantity, a sufficiently large quantity of light can be projected on the subject by the entire light source array unit, and hence, the three-dimensional measurement can be stably carried out. The pool can be filled and emptied using a pump. The CPU is set such that it jumps to the boot PROM at the time of startup of the embedded system.
