                                POWER OF ATTORNEY

With respect to holdings of and transactions in securities issued by Ouster,
Inc. (the "Company"), the undersigned hereby constitutes and appoints the
individuals named on Schedule A attached hereto and as may be amended from time
to time, or any of them signing singly, with full power of substitution and
resubstitution, to act as the undersigned's true and lawful attorney-in-fact
to:

1.    prepare, execute in the undersigned's name and on the undersigned's
      behalf, and submit to the United States Securities and Exchange
      Commission (the "SEC") a Form ID, including amendments thereto, and any
      other documents necessary or appropriate to obtain and/or regenerate
      codes and passwords enabling the undersigned to make electronic filings
      with the SEC of reports required by Section 16(a) of the Securities
      Exchange Act of 1934, as amended, or any rule or regulation of the SEC;

2.    execute for and on behalf of the undersigned, Forms 3, 4, and 5 in
      accordance with Section 16 of the Securities Exchange Act of 1934, as
      amended, and the rules thereunder;

3.    do and perform any and all acts for and on behalf of the undersigned
      which may be necessary or desirable to complete and execute any such Form
      3, 4, or 5, complete and execute any amendment or amendments thereto, and
      timely file such form with the SEC and any stock exchange or similar
      authority; and

4.    take any other action of any type whatsoever in connection with the
      foregoing which, in the opinion of such attorney-in-fact, may be of
      benefit to, in the best interest of, or legally required by, the
      undersigned, it being understood that the documents executed by such
      attorney-in-fact on behalf of the undersigned pursuant to this Power of
      Attorney shall be in such form and shall contain such terms and
      conditions as such attorney-in-fact may approve in such attorney-in-facts
      discretion.

The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary, or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might
or could do if personally present, with full power of substitution and
resubstitution or revocation, hereby ratifying and confirming all that such
attorney-in-fact, or such attorneys-in-fact substitute or substitutes, shall
lawfully do or cause to be done by virtue of this Power of Attorney and the
rights and powers herein granted.

The undersigned acknowledges that the foregoing attorneys-in-fact, in serving
in such capacity at the request of the undersigned, are not assuming, nor is
any Company assuming, any of the undersigned's responsibilities to comply with
Section 16 of the Securities Exchange Act of 1934, as amended.

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4, and 5 with respect to the
undersigned's holdings of and transactions in securities issued by the Company,
unless earlier revoked by the undersigned in a signed writing delivered to the
foregoing attorneys-in-fact.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 10th day of February, 2023.
