i think the show you're talking about is "Automan".
here's a quote from the website:
"Walter Nebicher is a policeman. He is also an expert in computers. He developed a highly sophisticated hologram named Automan, which helps him fight crime. Automan has an assistant camed Curser that can create holographic objects such as a car, helicopter or any other object needed by Walter or Automan to fight crime."
